Fought September 20, 1620, between the Poles under Gratiani, and the Turks, under Osman II. The Poles were completely defeated. Jellalabad (First Afghan War). This fortress was besieged by the Afghans, under Mohammed Akbar Khan, March 11, 1842, after the destruction of General Elphinstone’s force in the Khoord Cabul pass. It was defended by a small British garrison, under General Sale. Akbar led his whole army to the assault, but was gallantly repulsed, and then sat down to besiege the place in form. An attempt to relieve it by Brigadier Wyld, in January, 1843, failed, Wyld being defeated in the Khyber Pass by the Khyberis. The garrison meanwhile made several successful sorties, and on April 7, drove Akbar Khan out of his entrenchments, with a loss of all his guns, and many men, forcing him to raise the siege. All chance of a renewal of the investment was ended by the arrival on the 18th, of a strong relieving force, under General Pollock. Jemappes (Wars of the French Revolution). Fought November 6, 1792, between the Austrians, under the Archduke Albert, and the French, under Dumouriez.

This name is generally given to the two battles fought October 14, 1806, by the two wings of the French army under Napoleon, at Auerstadt and Jena. At Auerstadt the Prussian left, 70,000 strong, under the Duke of Brunswick, was encountered by the French right, under Davoust, with slightly inferior numbers, and after very severe fighting, were defeated, the Duke of Brunswick being killed. Napoleon, on the left, with 100,000 men, attacked the Prince of Hohenlohe with 70,000 Prussians, and after a sternly fought engagement, drove him from the field. The two defeated armies, retiring by converging routes upon Weimar, the retreat became a rout, and Napoleon’s pursuing cavalry caused them further heavy losses. The Prussians in the two actions lost 22,000 killed and wounded, 18,000 prisoners and 300 guns. Twenty generals were killed, wounded or captured. The French lost 11,000 killed and wounded, 7,000 of whom fell at Auerstadt. Jersey.
