The Battle of Kuwait International Airport occurred on February 27, 1991 during the 1st Gulf War.
 It was a tank battle between the United States and Ba'athist Iraq.
 Despite being a very large battle it is often overlooked compared to the other battles which took place during the war.
 No less than elements of 18 divisions total participated in this battle.
 U.S. Army Special Forces units and multiple Iraqi Commando units were also in theatre.
 In reality the battle took place over a span of three days despite the primary battle at Kuwait International Airport lasting only one day.
 Much of the combat actually took place en route to the airport.
 The battle featured the "Reveille Engagement" which went on to become the biggest and fastest tank battle in United States Marine Corps' entire history.
The Battle of Pered, fought on 20–21 June 1849, was one of the battles which took place in the Summer Campaign of the Hungarian War of Independence from 1848 to 1849, fought between the Hungarian Revolutionary Army and the Habsburg Empire helped by Russian troops.
 The Hungarian army was led by General Artúr Görgei, while the imperial army by Lieutenant field marshal Julius Jacob von Haynau.
 After a several preliminary minor battles of the Hungarian and Austrian troops along the Vág river, in which the attacking Hungarians could not achieve a success, Görgei took the command of his troops, and after receiving reinforcements, at 20 June, put his troops to attack again towards West.
 Although the II.
 Hungarian army corps occupied in heavy fights the village of Pered, the other two corps (the III.
 and the VIII.)
 were unsuccessful, and could not advance.
 The angered Görgei removed the commander of the III.
 corps, General Károly Knezić because of his inactivity, and Colonel Lajos Asbóth, the commander of the II.
 corps who, in contrast to Knezić, was the only commander who successfully accomplished his duties.
 While Knezić's place was taken by Colonel Károly Leiningen-Westerburg, who was a great choice, Asbóth's place was taken by Colonel József Kászonyi, who was an explicitly bad choice.
 Haynau, who in the first day of the battle was moving the bulk of his troops to cross the Danube in order to start an attack on its southern bank, sent three of his corps, which were still on the northern bank, to repel the Hungarian forces.
 The two Austrian (II., IV.)
 and one Russian (Panyutin's) corps started their attack at 21 June, and forced the Hungarians to retreat from Pered and Zsigárd, which forced Görgei to order his troops to retreat from the battlefield.
The Battle of Nablus took place, together with the Battle of Sharon during the set piece Battle of Megiddo between 19 and 25 September 1918 in the last months of the Sinai and Palestine Campaign of the First World War.
 Fighting took place in the Judean Hills where the British Empire's XX Corps attacked the Ottoman Empire's Yildirim Army Group's Seventh Army defending their line in front of Nablus.
 This battle was also fought on the right flank in the Jordan Valley, where Chaytor's Force attacked and captured the Jordan River crossings, before attacking the Fourth Army at Es Salt and Amman capturing many thousands of prisoners and extensive territory.
 The Battle of Nablus began half a day after the main Battle of Sharon, which was fought on the Mediterranean section of the front line where the XXI Corps attacked the Eighth Army defending the line in front of Tulkarm and Tabsor and the Desert Mounted Corps which rode north to capture the Esdrealon Plain.
 Together these two battles, known as the Battle of Megiddo, began the Final Offensive of the war in the Sinai and Palestine campaign.
The Battle of Selinus, which took place early in 409 BC, is the opening battle of the so-called Second Sicilian War.
 The 10-day-long siege and battle was fought in Sicily between the Carthaginian forces under Hannibal Mago (A king of Carthage of the Magonid family, not the famous Hannibal of the Barcid family) and the Dorian Greeks of Selinus.
 The city of Selinus had defeated the Elymian city of Segesta in 415 BC, an event that led to the Athenian invasion of Sicily in 415 BC and ended in the defeat of Athenian forces in 413 BC.
 When Selinus again worsted Segesta in 411 BC, Carthage, responding to the appeal of Segesta, had besieged and sacked Selinus after the Carthaginian offer of negotiations had been refused by the Greeks.
 This was the first step towards Hannibal's campaign to avenge the Carthaginian defeat at the 1st battle of Himera in 480 BC.
 The city of Selinus was later rebuilt, but never regained her former status.
The Battle of Hatvan was the first battle in the Spring Campaign of the Hungarian War of Independence from 1848–1849, fought on 2 April 1849 between the Habsburg Empire and the Hungarian Revolutionary Army.
 This battle was the start of the Hungarian offensive, which had the purpose to liberate the Central and Western parts, and the capital of Hungary, occupied by imperial forces.
 The Austrian force were led by General Franz Schlik, while the Hungarians were led by Colonel András Gáspár, and lieutenant-colonel Ernő Poeltenberg.
 In the Hungarian army fought also the Polish Legion under the lead of Colonel Józef Wysocki.
 The Hungarians were victorious, and advanced towards the Hungarian capitals, Buda and Pest.
The Battle of Vác, fought on 10 April 1849, was one of the two important battles which took place in Vác in the Spring Campaign of the Hungarian War of Independence from 1848–1849, fought between the Habsburg Empire and the Hungarian Revolutionary Army.
 This battle was the starting point of the second phase of the Spring Campaign, which had the purpose of relieving the fortress of Komárom from the imperial siege, and with this to encircle the Habsburg imperial forces headquartered in the Hungarian capitals of Buda and Pest.
 The Hungarians won the battle, in which the Austrian commander Major General Christian Götz was fatally wounded, dying after the battle.
 His body was buried by the Hungarian high commander Artúr Görgei with military honors, this being one of the examples of gallantry and high respect for the fallen enemy hero in the Hungarian War for Independence.
The Battle of Kosovo took place on 15 June 1389 between the army led by the Serbian Prince Lazar Hrebeljanović and the invading army of the Ottoman Empire under the command of Sultan Murad Hüdavendigâr.
 The army under Prince Lazar consisted of his own troops, a contingent led by Serbian nobleman Vuk Branković, and a contingent sent from Bosnia by King Tvrtko I, commanded by Vlatko Vuković.
 Prince Lazar was the ruler of Moravian Serbia, and the most powerful among the Serbian regional lords of the time, while Vuk Branković ruled District of Branković located in a part of Kosovo and other areas, recognizing Lazar as his overlord.
 The battle was fought on the Kosovo Field, in the territory ruled by Branković, in what is today Kosovo.
 Its site is about 5 km northwest of the modern city of Prishtina.
The Second Battle of Kosovo (Hungarian: "második rigómezei csata", Turkish: "İkinci Kosova savaşı") (17–20 October 1448) was a land battle between a Hungarian-led Crusader army and the Ottoman Empire at Kosovo Polje.
 It was the culmination of a Hungarian offensive to avenge the defeat at Varna four years earlier.
The Battle of Varna took place on 10 November 1444 near Varna in eastern Bulgaria.
 The Ottoman Army under Sultan Murad II defeated the Hungarian–Polish and Wallachian armies commanded by Władysław III of Poland (also King of Hungary), John Hunyadi (acting as commander of the combined Christian forces) and Mircea II of Wallachia.
 It was the final battle of the Crusade of Varna.
The Battle of Canal du Nord was part of a general Allied offensive against German positions on the Western Front during the Hundred Days Offensive of World War I.
 The battle took place in the Nord-Pas-de-Calais region of France, along an incomplete portion of the Canal du Nord and on the outskirts of Cambrai between 27 September and 1 October 1918.
 To avoid the risk of having extensive German reserves massed against a single Allied attack, the assault along the Canal du Nord was undertaken as part of a number of closely sequenced Allied attacks at separate points along the Western Front.
 It began one day after the Meuse-Argonne Offensive, one day before an offensive in the Flanders region of Belgium and two days before the Battle of St. Quentin Canal.
