# German Antiguerrilla Operations in the Balkans (1941-1944)/Chapter 7

CHAPTER 7
OPERATIONS (JANUARY–AUGUST 1943)
I. Yugoslavia
It was evident that neither the Pavelitch government nor the Italian forces in Croatia could cope with the widespread activities of the Partisans. Accordingly, it devolved upon General Lueters, Commander of German Troops in Croatia, to take appropriate measures.
General Lueter's first large-scale action was Operation WEISS. This was to be executed in conjunction with Italian forces, with the mission of annihilating strong Partisan units in the mountainous region west and northwest of Sarajevo. The operation was to be completed in three phases, with Italian troops holding zone two on the Italian side of the demarcation line and allowing the Germans to move into zone three, evacuated some time previously and heavily infiltrated by the guerrillas.
The German force committed to WEISS included the 7th SS Mountain and 717th Infantry Divisions, the recently arrived 369th Infantry Division, and a regiment of the 187th Infantry Division. The Italian force was the V Corps of the Italian Second Army. In sharp fighting in the first phase of WEISS, the Germans and their allies inflicted more than 8,500 casualties on the Partisans, taking 2,010 prisoners. The German losses totalled 335 dead and 101 missing, with Croatian losses in proportion; Italian casualties were markedly lighter, since the Italian units lacked aggressiveness and the proper balance in heavy weapons to engage in sustained fire fights. WEISS I was concluded on 18 February, and the divisions immediately regrouped for the second phase, to be completed by mid-March.
Heavy fighting marked the opening of WEISS II. Additional troops of the VI Corps in Montenegro arrived to bolster the Italian force, but substantial numbers of Partisans managed to break through the Italian line and escape south and southeast into the wilder mountain regions of Hercegovina, Montenegro, and eastern Bosnia. Dispersing into almost inaccessible areas, the Partisan command group and numerous individuals managed to elude their pursuers. WEISS III, the Italian part of the operation, was completely unsuccessful.
WEISS was satisfactory from the German point of view in that the important bauxite-producing area of Yugoslavia was cleared of Partisans and heavy casualties were inflicted among them in the proc​ess. Moreover, the guerrillas were driven into barren and sparsely populated mountain areas offering little sustenance and few recruits to replace the battle losses.
The Chetniks became a matter of sharp contention between German and Italian commanders during the course of Operation WEISS. In fact, the Italians had been requested to disarm their Chetnik auxiliaries as part of WEISS III. However, regarded as allies by the Italians, many Chetnik units were supplied with arms and ammunition and given important missions in the conduct of operations.
Since repeated requests to disarm these Chetniks were met with evasion, local German commanders were instructed to disarm and detain as prisoners any Chetniks encountered in their areas of responsibility. Strong German protests to Mussolini finally had the desired effect, and the Italian field commanders were directed to cease delivery of arms and munitions to the Chetniks and to disarm them as soon as the Partisans had been destroyed.
To forestall any repetition of the events that made necessary such a large-scale undertaking as Operation WEISS, the German Armed Forces High Command directed the Commander-in-Chief, Southeast, to retain forces in that part of Croatia just cleared of the Partisans and to secure the bauxite mines in Dalmatia, in conjunction with the Italians. The commander of German forces in the Balkans was further directed to accelerate the organization of Croatian units and to keep the matter a secret from the Italians. Presumably, these measures would provide a large number of native troops to replace German units.
However, it soon became obvious that the situation would not be improved by such measures as the expansion of the demoralized Croat police and military forces. Large concentrations of Chetniks, including those supported by the Italians, formed a constant threat to German forces in the event of an Allied landing, and the Commander-in-Chief, Southeast, directed that Operation SCHWARZ, under the Commander of Troops in Croatia, be undertaken in May and June to destroy the Chetniks in Hercegovina and Montenegro.
In addition to the divisions he already had assigned to him, the Commander in Croatia received the 1st Mountain Division from the Russian front and a reinforced regimental combat team of the 104th Light Division from the German forces in Serbia for the projected operation. Achieving surprise, the German forces inflicted heavy casualties on the Chetniks, capturing their commander in Montenegro, Major Djurisic, with 4,000 men, and forcing Mihailovitch to flee back into Serbia with the battered remnants of his command.
​There were also disorders in Serbia during this period. For the first three months of the year, 985 incidents were reported, including sabotage, attacks on native officials and police, and attacks on small German and Bulgarian troop units and installations. In a particularly unenviable position were the local officials, forced to remain in office by the Germans and regarded as collaborators by both Chetniks and Partisans. Fifty-eight were murdered during the first quarter of 1943, and 197 town halls were burned or damaged. In reprisal, in addition to burning some villages and levying fines in livestock, the occupation authorities ordered the shooting of several hundred hostages from among those arrested on suspicion of being members or supporters of the Chetnik and Partisan movements. These ruthless measures had the desired effect for a time, but could not prevent the regrouping of both Chetniks and Partisans as soon as the thinly spread German or Bulgarian forces had left a particular area.
Retaliation for attacks on the Bulgarian forces was even swifter, in many cases, than the reprisals meted out by the Germans. In one such incident, in March of 1943, 32 Bulgarians were killed and 26 wounded in an attack south of Skoplje. In their fury, the Bulgarian troops shot 288 persons in the vicinity, burned 550 houses, and placed 715 person under arrest. The readiness of the Bulgarians to shoot suspects without investigation of any kind finally prompted the German Commander in Serbia to request a careful preliminary examination of each case before an execution was carried out.
II. Greece
Receiving supplies and equipment by air through the 12 British liaison officers assigned by the British Middle East forces, the EDES organization had expanded from the 98 men with which it had commenced operations in 1942 to some 600 men two months later. This growth was accelerated by British broadcasts to Greece and the award of a high British decorataion to the EDES commander. The rapid growth of the force soon made it necessary to form a provisional battalion.
By March 1943, some 4,000 strong, EDES found it necessary to form more battalions and several regiments, some of which were commanded by former Greek Army officers. By July 1943, EDES had 8 to 10 units of two regiments each, the regiments each consisting of 2 battalions, and a total strength of 7,000 men. The headquarters and bulk of these forces were located in Epirus, and smaller groups operated in Thessaly and the Peloponnesus.
ELAS, leaderless until Sarafis assumed command in May 1943, was restricted to that time to a series of uncoordinated attacks. Under its new commander, however, ELAS soon emerged as an organized force. ​With an estimated seven "divisions" and 12,000 men by mid-1943, ELAS units were active the length of Greece, with the exception of the Pindus Mountains area, held by EDES.
The initial successes of the guerrillas against the occupation forces in 1943 were brought to an abrupt end when the German 1st Mountain Division moved from Serbia into Greece and Albania in June to bolster the Italian effort. The guerrillas, with ample warning by their excellent intelligence system, planned a heavy blow against the new enemy before he could establish himself in his occupation role.
The guerrilla operation was to be launched as the mountain troops moved south through the village of Leskovic, high in the mountains along the Greek-Albanian frontier, on the Albanian side. (Map 4.) At that time, however, the border was crossed at will by local inhabitants, and the operation was primarily a Greek undertaking.
As was their custom, the guerrillas cleared the village of all inhabitants, then placed their own men in position in the buildings along the main street. Their plan was to allow the advance guard to pass, and then to fire on the main body when the troops were confined to the street and roadway. A large force of guerrillas would then emerge from hiding places in the hills nearby to complete the destruction of the demoralized Germans.
Instead of marching blindly into the village, however, the Germans first enveloped it from either flank, and a number of the guerrillas opened fire prematurely. Deploying rapidly, the main body of the mountain troops surrounded Leskovic and shelled it thoroughly before launching their assault. The guerrilla force in hiding outside the village was routed by artillery fire when it attempted to relieve the ambushers, and Leskovic was reduced in a house-to-house operation. The stone construction of the houses afforded considerable protection to the besieged guerrillas, who inflicted heavy casualties on the mountain troops before the latter could bring a sufficient number of infantry and antitank guns into action to batter down their positions.
A number of the irregulars escaped by posing as fleeing civilians while the battle was at its height. When the Germans recognized their opponents at close range, however, they halted everyone attempting to leave the village, and soon held a motley collection of ragged men and youths. Examinations of these prisoners and of the bodies found in the rubble of Leskovic revealed most of the guerrillas to have been in civilian clothing or parts of German and Italian uniforms, with their only insignia a small hammer and sickle. The aggressive attitude of the new occupation troops, with their heavier firepower and greater battle experience, soon discouraged such ventures as the attack at Leskovic, and for a time EDES also ceased all active operations against them. However, in deference to the British Middle East ​forces, Zervas could not openly accept the German offer of a truce. ELAS, on the other hand, persisted with small-scale attacks on individuals and small parties.
III. The German Situation by Mid-1943
With both Yugoslav and Greek guerrillas withdrawn from large-scale operations for the moment, the Germans hastened to take steps to secure the Balkans against a threatening Italian collapse or surrender. Arrangements were made to replace Italian garrisons with German troops, and German forces were disposed in locations from which they could move quickly to contest Allied landings. As directed by the new chief of the Supreme General Staff, Generale D'Armata (General) Vittorio Ambrosio, Italian units were to withdraw without delay, ostensibly for the defense of Italy against a threatening Anglo-American invasion. In many cases, Italian units left their assigned areas before the arrival of their German relief, and the Germans had to drive out infiltrating guerrillas before occupying their new positions.
Various expedients were attempted by the Germans in an effort to fill the power vacuum the Italian withdrawal was causing. One such measure was the westward extension of the Bulgarian occupation zones in Greece and Yugoslavia. However, the certain resentment of the population and the refusal of King Boris to move Bulgarian troops farther away from the Turkish-Bulgarian border made necessary the cancellation of these plans. Deeply concerned about the possibility of Turkey's entering the war on the Allied side, the Bulgarians kept idle major forces of first-line troops while sending second-rate divisions of older reservists to garrison their zones of Greece and Yugoslavia.
Nor was the reorganization of the Croat Army and security forces of any avail. Except for the Legion troops under German command, the Croatian military and security forces were confined to the larger centers of population. Desertions became more frequent, and even Legion troops could no longer be depended upon for missions not including a hard core of German units.
It was obvious that more German troops would be required if the Balkans were to be held. Temporarily, it would suffice to have satellite and puppet military and security forces hold the interior while German units moved to the coastal areas and likely invasion points. However, it would eventually be necessary to have reliable and combat-experienced troops to replace the puppet units or to furnish a cadre to stiffen them in operations. Accordingly, plans were made to strengthen the German forces by the induction of more ethnic Germans, by organizing several new divisions, and by bringing in a number of divisions and higher commands from other fronts and from German-occupied Europe.
​By late June the 1st Panzer Division had arrived from France, where it had refitted after commitment on the northern and central Russian fronts. The newly formed LXVIII Corps headquarters, in army group reserve, was assigned the 1st Panzer and 117th Light Divisions, and given the mission of defending the Peloponnesus. Two other divisions were in the process of formation, the 100th Light Division in Croatia and the 297th Infantry Division in Serbia. Additional Bulgarian troops also arrived, to bring the number of Bulgarian divisions in the occupied Balkans to seven.
As of the end of June, the Germans had a total of three Bulgarian, one Italian, and 12 of their own divisions scattered throughout those areas of the Balkans under nominal German control. Several separate regiments and security battalions, the Russian Guard Corps, and a number of coastal defense battalions and supporting units were also available, though most were of limited combat potential. The Germans planned to commit their Croatian and Serbian puppet and security troops only in an auxiliary role.
The population of the areas held by the Germans, their weakening Italian allies, the Bulgarians, and the Pavelitch government totalled almost twenty-five million persons. In Greece, the occupiers were opposed by ELAS and EDES forces estimated at 18,000 to 20,000 men; in Yugoslavia by 50,000 to 60,000 Partisans, and 12,000 to 15,000 Chetniks (mobile units only); in Albania, by a total estimated to be as many as 20,000, with the strongest group that of the Communist leader, Enver Hoxha.
Many excesses of the occupation troops, particularly of the Croat Ustascha, had alienated large segments of the population. This changing attitude was promptly exploited by the guerrilla leaders, particularly the communists, who adopted a nationalist and popular front appeal to gain sympathy and support. Many former collaborationists were forgiven and accepted into the guerrilla bands, their ranks further swelled by Italian and Bulgarian deserters.
Eventual Allied victory had also become more obvious to the mass of the Balkan population by mid-1943, and few desired to be associated with a losing cause and reprisals. The judicious use of gold by the Allied liaison teams had brought a number of independent mountaineer chieftains into the guerrilla camp, and the promise of weapons secured the loyalty of many clans in the more remote regions.
The successful Allied lodgment in Sicily on 10 July and the worsening internal situation in the Balkans again raised the specter of enemy landings along the Adriatic, on the Aegean islands, or against the western coast of Greece. Accordingly, the German Armed Forces High Command, on 26 July, issued Directive No. 48, introducing ​major organizational changes and centralizing authority for the defense of the entire Balkan Peninsula. Generalfeldmarschall (Field Marshal) Maximilian von Weichs, formerly commander of Army Group B in southern Russia, became Commander-in-Chief, Southeast, replacing General Loehr, whose Army Group E was now restricted to Greece and the Greek islands. Marshal von Weichs, with headquarters at Belgrade, also directly commanded Army Group F, controlling all occupational troops in Yugoslavia and Albania.
One issue with the Italians was settled, at least temporarily, by the inclusion of the Italian Eleventh Army under the German theater command. In turn, the German LXVIII Corps, replacing the Italian VIII Corps on the Peloponnesus, came under control of Eleventh Army. Also, German forces in areas occupied by the Italians were placed under Italian command for tactical purposes.
Like similar directives issued earlier, the primary mission assigned the new Commander-in-Chief, Southeast, was to prepare the coastal defense of the Greek islands and mainland. To secure his rear area while so engaged and to prevent the disruption of his supply line and the movement of reinforcements in the event of Allied landings, he was further directed to destroy the guerrilla forces operating the length of the peninsula.
A mobile task force of 2 armored, 2 mountain, and 2 light infantry divisions was to be concentrated along the rail line south of Belgrade. In addition to securing the most sensitive section of the Belgrade–Athens line, this centrally located force would be available for commitment against any major beachhead the Allies might succeed in effecting.
The Bulgarian 7th Infantry Division in Thrace was attached to the German command at Salonika, and the Bulgarian corps would come under German control in the event of an Allied landing. All German civilian and government agencies, with the exception of the two chief representatives of the Foreign Office, also became subordinate to the Commander-in-Chief, Southeast.
Measures to effect a more thorough reorganization of the German forces in Greece and Yugoslavia and to complete the transposition of some headquarters from administrative (territorial) to tactical status followed Directive 48. The headquarters of the XXII Mountain Corps was formed from a part of the personnel from the headquarters of the Military Commander, Southern Greece; the functions of this area commander were absorbed by the new Military Commander, Greece, whose headquarters was formed from the remaining personnel. The headquarters in Serbia was disbanded, the personnel being used to form the headquarters of the XXI Mountain Corps, assigned to Albania, and the Military Command, Southeast. A third corps head​quarters, the XV Mountain, was formed from personnel of the headquarters of the Commander of German Troops in Croatia; General Lueters assumed command of the new corps with many of his old staff.
Other corps headquarters formed at the time or moved into the area included the III SS Corps, V SS Mountain Corps, and the LI and LXIX Corps. One higher headquarters, that of Second Panzer Army, arrived from the Soviet Union and established its headquarters at Kragujevac, its mission to control the large mobile force to be formed in this central Balkan area south of Belgrade and to act as a mobile reserve to counter any Allied landings in force.
A number of small-scale operations were carried out against both Partisans and Chetniks throughout Yugoslavia during this period. In contrast to large-scale operations, these had the advantage of making easier the security of preparations and the achieving of surprise, and succeeded in keeping the irregulars constantly on the move. However, they had the disadvantage of allowing individual Partisans and Chetniks to slip through repeated encirclements and escape into areas recently combed by other units or where the occupation troops were not so active at the moment.
With the Italian ally about to join the enemy, the Commander-in-Chief, Southeast, was faced with the problem of holding extensive and rebellious areas with inadequate forces, while securing a long and exposed sea flank against an enemy having overwhelming naval and air superiority. Taking advantage of the situation, Partisan units became active in the Sarajevo area; in Albania, troops of the 100th Light Division had to be committed against guerrillas who had seized control of the Tirana airfield and were effectively blocking the landing of much-needed German reinforcements by air.
* ↑ The 704th, 714th, 717th, and 718th Infantry Divisions were reformed as light divisions in early 1943. Reference to them hereafter will be to the 104th, 114th, 117th, and 118th Light Divisions. Light divisions had an organization similar to that of the mountain divisions, but with additional motor transportation for employment on more level terrain.
* ↑ Divisions originally bearing these numbers had been destroyed at Stalingrad.
