On September 20, 1854, the Battle of the Alma took place. It was first major battle of Crimean War. British and French forces defeated the Russians. An excerpt from the article:
"In mid-September 1854, the allies landed 30,000 French soldiers, 26,000 British troops and 4,500 Turks at Eupatoria, a town on the Crimean peninsula. The plan was to march south and capture Savastopol, a heavily-fortified port city that served as the main naval base for Russia’s Black Sea fleet. A few days later, the allies took on the Russians at the battle of the Alma, which ended just three hours later with the Czar’s forces being routed. More than 5,700 Russian soldiers were killed, while the British and French lost 962 men, according to the Lancashire Infantry Museum."
