The Battle of Stameriena was fought in 1261 between the Novgorodian army of Stepan Volchkov and an army of the Teutonic Order (consisting mostly of English crusaders) in present-day Latvia.
The Teutonic Order had been forced on the defensive after the fall of their stronghold at Dunaburg, and the Russians began to push into Livonia. In 1261, one of their armies had been defeated at Karsava while attempting to invade the Pskov region, but they sent another one, led by Helmut von Modohn, to threaten the Novgorodian castle at Olysta. This army consisted mostly of English crusading knights who had come to the Baltics as part of the English noble Charles the Crusader's retinue.
The Novgorodian grand prince Stepan Volchkov and his army of 1,062 Russians intercepted the crusading army near the Russia-Latvia border at Stameriena. The Novgorodians positioned themselves on a hilltop, securing the high ground. They had only one troop of spearmen, while the rest of their army consisted of horse archers, foot archers, and a few cavalry militia. The English should have been able to destroy the Novgorodians, who lacked enough spearmen to have the upper hand, but the English knights were showered with arrows before they could meet the Novgorodians with their swords. When they charged the spearmen, they were outflanked by the Novgorodian cavalrymen and were both surrounded and butchered. 464 English knights were killed outright, while 360 were captured while attempting to flee. The Novgorodians took 20 English feudal knights, 55 dismounted English feudal knights, 273 English levy spearmen, and 12 burgher pikemen as prisoners, and they demanded a ransom of 1,998 florins from the Teutonic Order. However, the Order refused to pay their ransom, and the 360 captives were subsequently executed.
