Altendorf (Thirty Years' War).
Fought August 24, 1632, between Gustavus Adolphus, with 40,000 Swedes and Germans, and the Imperialists, of about equal numbers, under Wallenstein. Wallenstein was very strongly posted on the hill and in the ruined castle of the Altenwald, and after a day spent in fruitless assaults, the King was forced to retire, having lost about 2,300 in killed and wounded. The defenders admitted a loss of 70 officers and 2,000 men killed, besides wounded and prisoners.
