# Allied occupation of the eastern Adriatic

The occupation of the eastern Adriatic by the Allies of World War I was a military mission that followed the First World War and lasted from November 1918 to September 1921. Naval assets and troops of the United Kingdom, the Kingdom of Italy, France, and the United States were deployed to parts of the territory of former Austria-Hungary, especially the region of Dalmatia, the city of Rijeka, and coastal areas of the Kingdom of Montenegro. The occupation was intended to resolve a number of issues, including the disposal of assets of the Austro-Hungarian Navy and settlement of Italian territorial claims on the eastern coast of the Adriatic Sea. Those claims, largely corresponding to the award made under the Treaty of London used to entice Italy to enter the war on the side of the allies, conflicted with the territorial claims of the nascent Kingdom of Serbs, Croats and Slovenes (later renamed Yugoslavia) and its predecessor states, as well as the principle of self-determination outlined in the Fourteen Points of the US President Woodrow Wilson.
The allies divided the eastern Adriatic coast into four zones of occupation. The Italian zone was determined to correspond to the Treaty of London award, and centred on the cities of Zadar and Šibenik in northern Dalmatia. Central Dalmatia and the city of Split were assigned to the United States. Southern Dalmatia, between Dubrovnik and Kotor, and the coast of Montenegro became the French zone of occupation. The British were assigned to the Kvarner Gulf in the northern Adriatic, centred on the city of Rijeka. Italy claimed the city on the basis of the Treaty of London and on the principle of self-determination. Littoral areas outside the four zones of occupation were controlled either by Italian forces in Istria or by the Army of the Kingdom of Serbs, Croats and Slovenes (or the Royal Serbian Army before December 1918). All of the allied nations had military presences in major ports.
The occupation was marked by Italian efforts to pursue territorial claims and conflicts with civilian populations and local authorities in some areas. Otherwise, the local population in Dalmatia generally welcomed the Allies. In ethnically mixed Rijeka, the reception reflected the ethnic composition. The occupation of Rijeka in the British zone was characterised by takeover of the city by Gabriele D'Annunzio in September 1919. To prevent Rijeka from becoming a city-state, D'Annunzio proclaimed the Italian Regency of Carnaro and the allies retreated from the city. In the French zone, Italy and France came in conflict over support for preservation of Montenegro's independence or its inclusion in the Kingdom of Serbs, Croats and Slovenes, as well as over support for opposing factions in the January 1919 Christmas Uprising in Montenegro.
The reasons for the occupation were addressed by the transfer of the remaining Austro-Hungarian naval assets to Italy and the Kingdom of Serbs, Croats and Slovenes, and by the 1920 Treaty of Rapallo that determined the border between the two countries. The treaty also established the Free State of Fiume in the Rijeka area, prompting D'Annunzio's removal from the city by the Regia Marina.

## Background

In 1915, the Kingdom of Italy entered the First World War on the side of the Entente following the signing of the Treaty of London, which promised Italy territorial gains at the expense of Austria-Hungary. The treaty was opposed by representatives of the South Slavs living in Austria-Hungary, who were organised as the Yugoslav Committee. Following the 3 November 1918 Armistice of Villa Giusti, the Austro-Hungarian surrender, Italian troops moved to occupy parts of the eastern Adriatic shore that had been promised to Italy under the Treaty of London, ahead of the Paris Peace Conference. The State of Slovenes, Croats and Serbs, that was carved from areas of Austria-Hungary populated by the South Slavs, authorised the Yugoslav Committee to represent it abroad, and the short-lived state, which would soon seek union with the Kingdom of Serbia to establish the Kingdom of Serbs, Croats and Slovenes, laid a competing claim to the eastern Adriatic to counter Italian demands. This claim was supported with the deployment of the Royal Serbian Army to the area.
The Treaty of London's provisions were a major point of dispute between Italy and the remaining Entente powers at the Paris Peace Conference. The chief Italian representatives, Prime Minister Vittorio Emanuele Orlando and foreign minister Sidney Sonnino demanded enforcement of the treaty relying on application of the security principle, and the annexation of the city of Rijeka (Italian: Fiume) on the basis of self-determination. Orlando was prepared to abandon claims in Dalmatia, except Zadar (Italian: Zara) and Šibenik (Italian: Sebenico), while insisting on annexing Rijeka. Sonnino held a view that was summarised as "Pact of London plus Fiume", portraying the claim as a matter of Italian national honour.
The British and the French governments would not publicly endorse any claims exceeding those the treaty afforded while privately believing Italy deserved little because of its reserved attitude towards Germany in early stages of the war. Regarding Dalmatia, the British Prime Minister David Lloyd George supported a free-city status for only Zadar and Šibenik, while the French Prime Minister Georges Clemenceau supported such a status for only Zadar. Clemenceau and Lloyd George let the President of the United States Woodrow Wilson hold in check Italian ambitions in the Adriatic by advocating self-determination of the area in accordance with point nine of his Fourteen Points.
Wilson deemed the Treaty of London a symbol of perfidy of European diplomacy and held it invalid by application of the legal doctrine of clausula rebus sic stantibus due to fundamental changes of circumstances following the dissolution of Austria-Hungary.
According to the 1910 census, Croats comprised 80%, Serbs comprised 17%, and Italians comprised 3% of the Dalmatian population of 634,855. The region was administered from Zadar where the Diet of Dalmatia and regional government had their seats. In 1910, Zadar had a population of 13,247 and an Italian majority of 70%.

## Zones of occupation

The occupation forces were to be coordinated by the Naval Commission for the Adriatic, which consisted of admirals delegated by the four powers. Initially, the Adriatic Commission was chaired by the Italian Rear Admiral Vittorio Molà [it]. It was intended to manage peacekeeping, normalisation of civilian life and maritime transport, distribution of the Austro-Hungarian fleet and other related issues the Paris Peace Conference had permanently settled. The commission, which was established on the basis of the decision of the Allied Naval Council of the Supreme War Council on 5 November 1918, first met in Rijeka but was later moved to Venice and Rome.
The Adriatic Commission agreed on zones of occupation of the eastern Adriatic shores. The United Kingdom was to control the Kvarner Gulf, Italy would control northern parts of Dalmatia, The US would control the southern Dalmatian coast, and France would control the coasts of the southernmost part of Dalmatia, the Kingdom of Montenegro and the further-south coast of the Principality of Albania. The occupation plan was never fully enforced; only Italy deployed a large force to the area. The assignment of the Italian zone was the result of a fait accompli. Italy interpreted the armistice terms as allowing them to establish the armistice line in accordance with the claims laid out in the Treaty of London. Italy had already established a firm foothold in the claimed area by the time the zones were defined in Venice on 16 November in a meeting of the Adriatic Commission that was chaired by Admiral Paolo Thaon di Revel. Other sources say the zones were defined on 26 November at a commission meeting in Rome.

## British zone
### End of the Austro-Hungarian rule

In late October 1918, the governing organ of the State of Slovenes, Croats and Serbs, the Zagreb-based National Council of Slovenes, Croats and Serbs, appointed Rikard Lenac to take over administration of Rijeka on behalf of the newly proclaimed state. The move was coordinated with the administratively separate suburb of Sušak. The takeover of authority occurring on 29 or 31 October, according to varying sources. Military authority in Rijeka and Sušak was assumed by Lieutenant Colonel Petar Teslić, who commanded eight battalions of the 79th Infantry Regiment of the former Austro-Hungarian Common Army normally based in Otočac, and National Guard volunteers, largely consisting of high-school pupils. Leading ethnic Italians living in the city established the Italian National Council of Fiume (Italian: Consiglio Nazionale delli Italiani di Fiume) and declared the desire to incorporate the city into Italy. They dispatched a delegation to Revel in Venice to request aid. Lenac asked Zagreb to send troops as well. There were clashes between Italian and South Slavic communities in the city, each side claiming the city on the basis of the self-determination principle. While Italy said there was an Italian majority in the city within the boundaries of the former Austro-Hungarian Corpus separatum, the South Slavs said the entire city, including the suburb of Sušak, had a South Slavic majority.

### Occupation of Rijeka

On 2 November 1918, a group of United States Navy ships sailed into the Port of Rijeka. The next day, they were followed by a French and a British force. Colonel Sydney Capel Peck led the British mission to Rijeka. On the same day, the Inter-Allied Command was established in Rijeka, ostensibly to prevent further ethnic violence. On 3 November, the day the armistice was signed, Italian armed forces gained control of much of the nearby Istria peninsula, including the cities of Trieste, Rovinj (Italian: Rovigno) and Pula (Italian: Pola). The Italian navy arrived in the Port of Rijeka on 4 November; the first group consisted of the battleship Emanuele Filiberto; and the destroyers Francesco Stocco, Vincenzo Giordano Orsini, and Giuseppe Sirtori. On 5 November, the French destroyers Touareg and Sakalave brought further reinforcements.
A 700-strong battalion of the First Yugoslav Volunteer Division led by Lieutenant Colonel Vojin Maksimović [sl] arrived from Zagreb on 15 November. Two days later, 16,000 Italian troops led by General Enrico Asinari di San Marzano [it] arrived. The battalion of the First Yugoslav Volunteer Division withdrew from the city and Teslić's troops were quickly disarmed. Some sources say Maksimović's withdrawal from the city was negotiated and made in exchange for the promise San Marzano's troops would not enter Rijeka but would remain in nearby Opatija. Although neither Rijeka nor Sušak were awarded to Italy under the Treaty of London, Italian authorities justified the deployment by referring to provisions of the armistice allowing occupation of additional territories required for strategic purposes. By early 1919, there were approximately 20,000 Italian troops in Rijeka. The Adriatic Commission discussed the Italian military dominance in the British zone and recommended the Paris Peace Conference to ensure military parity with other allied forces. Italy objected to the recommendation and the Paris Peace Conference did not act upon it.
On 6 July, the paramilitary Legione "Fiumana" [it] loyal to Italy clashed with French Annam troops in the city, killing 13 people. This action prompted the establishment of an international commission to determine the responsibility of the legionnaires. The commission recommended disbanding Legione "Fiumana" and reducing the number of Italian troops in the area to a single battalion as quickly as possible, leaving law enforcement to the British and the US forces. Those recommendations were not implemented but the 1st Regiment "Granatieri di Sardegna" was withdrawn from the city and moved to Ronchi dei Monfalcone near Trieste on 27 August 1919.

### D'Annunzio's rule

At the Paris Peace Conference, the United States, the United Kingdom, and France rejected Italian claims under the Treaty of London and claims regarding Rijeka. In June 1919, the Italian Orlando-led government was replaced by one led by Francesco Saverio Nitti. The new prime minister wanted to settle diplomatic issues abroad before concentrating on domestic issues. The Italian foreign minister Tommaso Tittoni agreed with the British and French that Rijeka should be a free city under the League of Nations, and that the entirety of Dalmatia should belong to the Kingdom of Serbs, Croats and Slovenes.
To pre-empt an unfavourable settlement of the issue, Gabriele D'Annunzio set out to Rijeka with approximately 200 veterans on the evening of 11 September. When the column reached Ronchi dei Monfalcone, it was joined by the Granatieri di Sardegna. The now-about 2,500-strong column proceeded towards Rijeka and arrived there the next day. In response to D'Annunzio's arrival, Italian and other allied troops withdrew from the city. D'Annunzio proclaimed the establishment of Italian Regency of Carnaro in the city the same day. His rule continued for fifteen months.

## Italian zone
### Capture of Zadar

On 4 November 1918, three Regia Marina ships set sail from Venice to Zadar, each carrying a platoon of the Arezzo Infantry Brigade to enforce the Italian claim against the city. Two of the three ships collided en route and turned back, leaving the torpedo boat 55 AS to continue alone. It arrived in Zadar at 2:30 p.m. and 66 troops disembarked 15 minutes later later, a few minutes before the armistice with Austria-Hungary was scheduled to come into effect. Upon arrival, the commanding officer of 55 AS Felice de Boccard declared he arrived on authority of the Entente and as an ally of Yugoslavia, and both ethnic Italians and Croats welcomed him.
Austro-Hungarian authorities had already been removed from the city on 31 October when the ad-hoc National Guard disarmed troops in the city barracks, removed government commissioner Mate Škarić and reinstated mayor Luigi Ziliotto, who had been removed from power in 1916. All Austro-Hungarian insignia were removed from the city streets, and the Italian, Croatian, and Serbian flags were raised at the City Guard building. The Serbian and Croatian flags were removed seven days later. The torpedo boat 68 PN and the destroyer Audace arrived at Zadar on 5 and 7 November, respectively.

### Governorate of Dalmatia

On 4 November, another group of Italian vessels departed from Brindisi and captured Vis (Italian: Lissa), Korčula (Italian: Curzola), Mljet (Italian: Melada), and Lastovo (Italian: Lagosta). By the end of 1918, Italian troops occupied the Dalmatian coast between and including Zadar and Šibenik, and the hinterland extending to Knin (Italian: Tenin) and Drniš (Italian: Dernis). They also occupied the islands of Hvar (Italian: Lesina) and Pag (Italian: Pago). On 19 November, General Armando Diaz appointed Vice Admiral Enrico Millo the governor of the newly established Governorate of Dalmatia. The governorate's seat was in Šibenik until January 1919, when it was moved to Zadar. The entire zone came under Italian control on 20 February 1919. The islands of Rab (Italian: Arbe) and Cres (Italian: Cherso) further north also came under Italian occupation.
Forces under Millo's control initially consisted of the Savona Infantry Brigade, several hundred Carabinieri and customs guards, and two battalions of marines. Millo requested reinforcements and received elements of the 24th Infantry Division "Pinerolo". Hoping to receive aircraft under his command, Millo ordered construction of an airbase near Zemunik Donji. The reinforcements brought the number of Italian troops deployed in the Italian zone and elsewhere along the eastern Adriatic coast to 29,000 by July 1919, but later in the year the force was reduced to about 15,000, and to 12,000 in mid 1920. Millo's requests for reinforcements were motivated by the possibility of a conflict with the army of the newly established Kingdom of Serbs, Croats and Slovenes, or the hostile population. The local non-Italian population often expressed dissatisfaction with the Italian military presence and several minor clashes occurred in 1919. Aiming to repeat his takeover of Rijeka, on 14 November 1919, D'Annunzio led a unit to Zadar but Millo took D'Annunzio's troops under his control. The reduction of the number of troops was caused by the Italian government's decision to reduce military expenses.
There were frequent deportations of the non-Italian population by the Italian forces. Millo suppressed national liberties, and authorities in the Italian zone systematically harassed non-Italians with methods including physical assaults and confiscation of ration cards. Non-Italian magistrates, physicians, teachers, and priests were particularly targeted with the aim of replacing them with ethnic Italians. To reduce the potential for visits to the zone, the occupation authorities made false reports of smallpox outbreaks. Most of the deported persons and those fleeing ethnic persecution went to the American zone. Such practices of Italian authorities largely ceased after Francesco Saverio Nitti replaced Orlando as the prime minister.

## American zone
### Provincial government

The American zone of occupation extended between the Italian and French zones; it lay between the Cape Planka and the island of Šipan (Italian: Giuppana) north-west of Dubrovnik (Italian: Ragusa). The US presence was largely confined to the city of Split (Italian: Spalato), while the armed forces of the Kingdom of Serbs, Croats and Slovenes controlled the rest of the coast in the zone. Italy successfully lobbied for British support for the potential Italian occupation of Split. Di Revel formally requested inter-allied occupation of Split on 14 November, a few days before the city was included in the American zone.
Austro-Hungarian government bodies had already been removed from the city in late October, and the National Council of Slovenes, Croats and Serbs appointed the provincial government of Dalmatia in Split. The provincial government consisted of Ivo Krstelj, Josip Smodlaka, and Vjekoslav Škarica; and deputies Prvislav Grisogono, Uroš Desnica, and Jerko Machiedo. In early 1919, General Miloš Vasić arrived in Split as the appointed delegate of the Government of Kingdom of Serbs, Croats and Slovenes to the provincial government of Dalmatia. Prior to the arrival of the allied navies, public safety in Split, which was affected by shortages of food and coal, had been entrusted to 200 National Guard volunteers organised into three companies. Because the US forces in Dalmatia were tasked with promoting Wilson's policy of self-determination, the US Navy protected and assisted the provincial government.

### Arrival of allies in Split

On 9 November, the first French vessels arrived in Split. The Destroyers Touareg and Sakalave sailed into the Port of Split for a day and were followed by the seaplane carrier Foudre. The population welcomed the French ships. At the same time, proponents of Italian annexation of Dalmatia hoisted Italian flags in the port, which led to civil unrest and conflict between the city's pro-Italian minority and its anti-Italian majority, and a gathered crowd forcefully removed the flags. An Italian torpedo boat sailed to the city but it had to anchor in the port because nobody would receive its mooring lines.
The Austro-Hungarian battleships Radetzky and Zrínyi sailed from Pula, and reached Split on 12 November to await surrender to Rear Admiral William H. G. Bullard. Bullard instructed Lieutenant Commander Edward Hazlett to go to Split with 200 troops and take control of the battleships. Sixteen US submarine chasers arrived in Split to accept the surrender, following which all but three proceeded to Šibenik. The two battleships hoisted US flags on 20 November. On the same day, a detachment of the Royal Serbian Army arrived by boat via Metković. The troops, which Major Stojan Trnokopović led, were provided accommodation in Gripe Fortress [hr]. By early 1919, the regular Army of the Kingdom of Serbs, Croats and Slovenes garrisoned the coastal settlements of Split, Trogir (Italian: Traù), and Omiš with a battalion in each, and one company was stationed in the inland town of Sinj.
Numerous allied ships made port calls in Split. By January 1919, those included the French destroyers Bambara, Foudre, Arabe, Hova, Sénégalais, and Janissaire, and the Arabis-class sloop Altair. In the same period, calls to the Port of Split were made by the Italian ships Carlo Mirabello, Alessandro Poerio, and Puglia, as well as US Navy's USS Israel. On 15 December, HMS Sheldrake was the first Royal Navy ship to arrive. By January 1919, it was followed by HMS Lowestoft and HMS Veronica. In February 1919, USS Olympia arrived in Split with Rear Admiral Philip Andrews aboard. USS Olympia took the role of the lead ship of the US forces, with USS Pittsburgh filling-in when Olympia was not in port. Andrews took over the command of the US Naval Forces in the Eastern Mediterranean from Rear Admiral Albert Parker Niblack on 26 March. Following Andrews's arrival, the US Navy rented a Katalinić family residential building in the port as office premises, and another house as a residence for Andrews and his wife. US Navy officers also opened a YMCA in the present-day building of the Split Archaeological Museum. British sailors occasionally played football matches against Hajduk Football Club. The United States financed the repair of roads, telegraph lines, storage facilities, buildings, and sports grounds used by the US Navy.

### Civil unrest

The civil unrest persisted during the allied occupation. Friction arose during the distribution of food and travel documents from the Italian cruiser Puglia because only the non-Italian population encountered real or perceived difficulties. There were occasional conflicts between Italian sailors, specifically the crew of Puglia, and the city's non-Italian population. Typical provocations involved hoisting of the flag of the Kingdom of Serbs, Croats and Slovenes in the port with assembled citizens saluting the flag while shouting insults to Italy. In response, Italian sailors and officers would verbally conflict with the citizens. This prompted Niblack to declare a ban on public gatherings, singing of patriotic songs and flag waving.
On 24 February 1919, a conference was convened in Split to examine allegations of persecution of the city's Italian minority presented in the Italian press. Bullard and Niblack attended the conference on behalf of the United States; Admiral Umberto Cagni and Rear Admiral Ugo Rombo on behalf of Italy; Rear Admiral Jean Ratyé [fr] on behalf of France; and Admiral Edward Buxton Kiddle representing the UK; and representatives of the city government were also present. At the conference, Rombo proposed landing a large Italian force to quell the civil unrest but Niblack, who held Italian navy and propaganda responsible, opposed the idea. The conference agreed on inter-allied patrols to ensure order in Split. The inter-allied patrols initially consisted of one officer, one petty officer and three enlisted men drawn from each allied navy, one soldier from the armed forces of the Kingdom of Serbs, Croats and Slovenes and one city police officer. Later, the patrols were reduced in strength by two-thirds as the situation gradually calmed. In addition to the allied patrols,the local police consisting of 65 officers supplemented by the National Guards militia maintained order in the city. Initially the National Guards were unreliable and even participated in looting, but they became an effective police auxiliary force by early 1919.

### Conflict in Trogir

D'Annunzio's takeover of Rijeka inspired a group of Italian officers to attempt the same in Trogir. On 23 September 1919, Count Nino Fanfogna led 200 Italian soldiers into the town. After a brief skirmish, the attackers disarmed the town garrison maintained by the Kingdom of Serbs, Croats and Slovenes. The government in Belgrade sent a protest to the Paris Peace Conference, while the provincial government of Dalmatia and Vasić complained to Andrews. He sent USS Olympia and USS Cowell under Captain David French Boyd, Jr. to Trogir.
Upon arrival, 100 US sailors and officers landed and took positions between Fanfogna and the troops defending Trogir. Boyd demanded Fanfogna's troops leave the town, giving them a two-hour ultimatum. They complied with Boyd's demand, withdrawing to Zadar. Andrews blamed both sides for the conflict, claiming the Italian force, inspired by D'Annunzio, wanted war, as did Lieutenant Colonel Milan Plesničar [sr] of the Army of the Kingdom of Serbs, Croats and Slovenes stationed in Split.

## French zone
### Landings in Kotor

On 10 November, the French, British, and Italian navies sailed into Kotor (Italian: Cattaro) and Rear Admiral Louis Caubet [fr] of France took command of the city in the name of the allies. The following day, three US Navy submarine chasers also arrived. By 15 November, Italy shipped two battalions of soldiers to the area. Local authorities protested against the landing of the Italian troops, declaring their intention to resist such a move if Italy alone was to deploy troops ashore. In turn, the allies asked the Italians not to proceed with the landing but the request was declined. Italy deployed the 137th Infantry Regiment "Barletta", which was led by Major General Demetrio Carbone [it], to Kotor and the 1st Infantry Regiment "San Giusto" to Bar. Italy also garrisoned the town of Ulcinj. To preserve the appearance of joint landing and prevent a clash, the allies assigned some sailors to disembark with the Italian soldiers. To avoid the landing appearing to be an exclusively Italian occupation, Caube asked the landing forces to proceed in small, unobtrusive groups but instead, the Italians held a ceremony with a prominent display of Italian flags and the playing of the Italian national anthem.
On 18 November, Italian transports brought in a further 3,000 troops and a battalion of the United States Army. The American battalion belonged to the 332nd Infantry Regiment that had been attached to the Italian army since its defeat in the 1917 Battle of Caporetto. It was intended to boost the Italians' defensive capacity and bolster morale. The regiment remained under Italian command following the armistice and its 2nd battalion was sent to Kotor. US sources concluded the Italian landings in the Bay of Kotor were designed to saturate the area with Italian troops with the aim of gaining politically dominant position in the area. The declared purpose of allied deployments to the Bay of Kotor was to secure Austro-Hungarian naval base in Kotor.

### Advance to Cetinje

Italy supported Montenegrin independence, viewing the prospective unified South Slavic state as a threat to its interests in the Balkans and the Adriatic. Italy exploited the Montenegrin question to extract concessions from Serbia. To support Italian policy of supporting the Montenegrin independence following contested elections for the Podgorica Assembly needed to decide on unification with Serbia, Carbone deployed a force to capture the nearby Montenegrin capital Cetinje on 23 November. For this task, he used two companies of the 332nd Infantry Regiment and two smaller Italian units. While en route, local officials approached Major Scanlon, the commanding officer of the two US companies, and explained to him the political situation. In response, Scanlon turned the US troops back to Kotor, leaving the Italians to proceed towards Cetinje. Upon reaching the Montenegrin border, the Italian troops clashed with a Serbian unit blocking the route and were forced to turn back. Carbone planned another attempt to capture Cetinje but was dissuaded following a heated discussion of the issue between Ratyé and Revel in Rome on 26–29 November. The French favoured Serbian (subsequently Kingdom of Serbs, Croats and Slovenes) control of Montenegro, and facilitated the deployment of 3,000 pro-Serbian Montenegrin troops in the area. The French-trained and supported troops included about 400 to be deployed in Kotor and 500 in Dubrovnik. A day after the proclamation of the Kingdom of Serbs, Croats and Slovenes on 2 December, Sonnino ordered the withdrawal of all Italian forces from Kotor. The order was later modified to allow some of the troops to remain.
On 3 January 2019, pro-independence Greens, a faction in the Montenegrin Christmas Uprising, approached Brigadier General Paul Venel, who had replaced Caubet as the French commanding officer in the zone, requesting the allies to occupy Cetinje and deny it to the forces of Kingdom of Serbs, Croats and Slovenes. Venel declined, prompting the Italian command in Montenegro to criticise the French for their bias. On 5 January, Venel sent French and American troops, and troops belonging to the newly proclaimed Kingdom of Serbs, Croats and Slovenes to Cetinje, taking control of the city two days later. At the same time, he intervened in an Italian effort to regain control of the village of Njeguši from the Greens. Carbone personally led Italian and US troops. Venel ordered the Italians to stop their advance while the US troops were allowed to proceed to the objective. Although he was acting on instructions from the commander of the Allied Army of the Orient General Louis Franchet d'Espèrey, Venel was relieved of command in February 1919 after further protests by the Italians and the Montenegrin government in exile. Venel was replaced by General Mathias Tahon.

### Handover of the Austro-Hungarian ships

The US troops left Montenegro in early 1919, while the French and the Italians limited their occupation to coastal areas of Bar and Ulcinj, the town of Virpazar on the shore of Lake Skadar, and Kotor at the southernmost tip of Dalmatia at the time, on the orders of d'Espèrey in April 1919. The remainder of Montenegro was left for the Army of the Kingdom of Serbs, Croats and Slovenes to occupy. French troops left Bar and Virpazar in March 1920, while the Italian troops remained there until the middle of 1920. The Austro-Hungarian fleet guarded in Kotor was handed to the Navy of the Kingdom of Serbs, Croats and Slovenes in July 1920.

## Aftermath

In June 1920, Nitti's government was replaced by the cabinet led by Giovanni Giolitti, who wanted to better concentrate on domestic issues and quickly settle foreign policy issues. The Kingdom of Serbs, Croats and Slovenes wanted to gain unobstructed access to Adriatic ports for commerce. It hoped for US assistance until Warren G. Harding and the Republican Party won the 1920 US presidential election. On 12 November, delegations of the two countries met in Rapallo and concluded a treaty on mutual borders. Italy received Istria, while the Kingdom of Serbs, Croats and Slovenes received Dalmatia excluding Zadar and several smaller islands. It was decided Rijeka and its immediate surroundings would become the Free State of Fiume.
In response to signing of the Treaty of Rapallo, the Italian Regency of Carnaro proclaimed a state of war, but the Italian Navy drove D'Annunzio from Rijeka in an intervention known as Bloody Christmas. Military rule persisted in the Italian zone until the end of December 1920, when a special civilian commissioner was appointed in Zadar, the seat of the Province of Zara, in the aftermath of the treaty. All allied troops left the French zone in December when the French left Kotor. The Treaty of Rapallo, along with the death of Nicholas I of Montenegro a few months later, marked the end of Italian support for Montenegrin resistance against the Kingdom of Serbs, Croats and Slovenes.
On 7 November, the US Navy towed Radetzky and Zrínyi to Šibenik, and handed the ships to Regia Marina. Although this completed the naval aspect of the US mission to the region, the United States Department of State requested the navy to remain in Split until Italian vessels withdrew from the city and until Italian troops withdrew from the Italian zone of occupation. The Adriatic Committee convened for the final time on 31 January 1921 to wind down its operations. On 26 April, Andrews left Split aboard USS Olympia. The US mission was concluded on 29 September 1921 as USS Reuben James, which was commanded by Rufus F. Zogbaum, Jr. as the senior officer in the Adriatic, sailed out of Split.
