The Battle of Havana was a naval engagement that took place between the British Caribbean squadron and a Spanish squadron based near Havana during the War of Jenkin's Ear.
 The battle occurred on the morning of the 12th and ended on the 14th October 1748.
 The belligerents consisted of two squadrons under the command of Admiral Don Andres Reggio of the Spanish Navy and Admiral Sir Charles Henry Knowles of the Royal Navy, respectively.
 The British succeeded in driving the Spanish back to their harbour after capturing the "Conquistador" and ran the vice-admiral's ship "Africa" on shore, where she was blown up by her own crew after being totally dismasted and made helpless.
 Although the advantage had clearly been with Knowles, he failed to use this to deliver a decisive blow.
 The battle was the last major action in the War of Jenkin's Ear which had merged with the larger War of the Austrian Succession.
The Battle of Sharqat (October 23–30, 1918) was fought between the British and the Ottoman Empire in the Mesopotamian Campaign in World War I, which became the last conflict in the between the belligerents before of the signing of the Armistice of Mudros.
Cherif Guellal (August 19, 1932 – April 7, 2009) was an Algerian businessman and diplomat, who fought in the Algerian independence movement and citizen of the United States.
The Treaties of Velasco were two documents signed at Velasco, Texas (now Surfside Beach, Texas) on May 14, 1836, between Antonio López de Santa Anna of Mexico and the Republic of Texas, in the aftermath of the Battle of San Jacinto on April 21, 1836.
 The signatories were Interim President David G. Burnet for Texas and Santa Anna for Mexico.
 The treaties were intended, on the part of Texas, to provide a conclusion of hostilities between the two belligerents and to offer the first steps toward the official recognition of the breakaway republic's independence.
The Fountain of Justice is a historic landmark in Bacolod City, Negros Occidental, Philippines.
 It marks the location where the house of Jose Ruiz de Luzurriaga used to stand.
 It was in this house that the surrender of Bacolod by Spanish authorities to the Filipino forces of General Aniceto Lacson took place on November 6, 1898, during the Negros Revolution.
 Luzurriaga acted as mediator between the two belligerents.
 Colonel Isidro de Castro, Spanish governor of Negros, signed the surrender document on behalf of the Spanish forces.
 The landmark now lies in front of the old Bacolod City Hall.
The Siege of Bangkok was a key event of the Siamese revolution of 1688, in which the Kingdom of Siam ousted the French from Siam.
 Following a coup d'état, in which the pro-Western king Narai was replaced by Phetracha, Siamese troops besieged the French fortress in Bangkok for four months.
 The Siamese were able to muster about 40,000 troops, equipped with cannon, against the entrenched 200 French troops, but the military confrontation proved inconclusive.
 Tensions between the two belligerents progressively subsided, and finally a negotiated settlement was reached allowing the French to leave the country.
The Dano-Swedish War of 1658–60 (Danish: "Anden Karl Gustav-krig" , Swedish: "Karl X Gustavs andra danska krig" , Dutch: "Zweeds-Nederlandse Oorlog" ) was a war between Denmark–Norway and Sweden.
 It was a continuation of an earlier conflict between the two belligerents which had ended just months earlier, after Sweden and Denmark brokered a peace agreement in Roskilde in 1658.
 In the aftermath of that conflict, the Swedish king Charles X Gustav desired to add the province of Royal Prussia in Poland to the Swedish realm, but his position in the region was not strong enough with the opposition of Brandenburg and Austria.
 However, the Danes stalled and prolonged the fulfillment of some provisions of the earlier peace; the Swedish king decided to use this as a pretext to attack with an ambitious goal: to vanquish Denmark as a sovereign state and raze the capital of Copenhagen.
 A quick and decisive defeat of Denmark was however only seen as a means to a greater end.
 The long-term goal was to wage war in Europe without fearing Danish interference.
The Algerian War, also known as the Algerian War of Independence or the Algerian Revolution (Arabic: الثورة الجزائرية‎ ‎ "Al-thawra Al-Jazaa'iriyya ";, Berber: ;, French: "Guerre d'Algérie" or "Révolution algérienne ") was a war between France and the Algerian National Liberation Front (French: "Front de Libération Nationale" – FLN) from 1954 to 1962, which led to Algeria gaining its independence from France.
 An important decolonization war, it was a complex conflict characterized by guerrilla warfare, maquis fighting, and the use of torture by both sides.
 The conflict also became a civil war between the different communities and within the communities .
 The war took place mainly on the territory of Algeria, with repercussions in metropolitan France.
The Battle of Valverde, or the Battle of Valverde Ford from February 20 to February 21, 1862, was fought near the town of Valverde at a ford of Valverde Creek in Confederate Arizona, in what is today the state of New Mexico.
 It was a major Confederate success in the New Mexico Campaign of the American Civil War.
 The belligerents were Confederate cavalry from Texas and several companies of Arizona militia versus U.S. Army regulars and Union volunteers from northern New Mexico and the Colorado Territory.
The conflict between the dynasties of the Capetians and Plantagenets covers a period of 100 years (1159-1259), during which the Kingdom of France fought against the Angevin Empire.
 This conflict is also called by some historians, the "First Hundred Years War."
 The conflict is primarily French, since both dynasties were French, the nobles that made up the English army were essentially of French origin, and the foot soldiers of the English king were local recruits in France (Anjou, Guyenne, Normandy, Brittany etc.).
 At this period, the English king's continental possessions were considered more important than his island possessions, and significantly greater than even those of the French sovereign, even if the latter was the overlord of the former for most of the possessions he held on the continent.
 And the official language of the two belligerents is the French of that time.
 French also remained the official language of England until 1361.
 Such is the origin of the expressions that can still be found today on the shields and coat of arms of the English monarchy "Honi soit qui mal y pense" and "Dieu et mon droit".
 The English kings, who were of French origin, took wives from France from the 11th to the 15th century.
 Very rare are those who married a woman of another country, including the cadet branches.
 Hence the Plantagenet monarchs were ethnically French.
