The Battle of Rain (also called the Battle of the River Lech or Battle of Lech) was fought on April 15, 1632, during the Thirty Years' War. It was the second meeting between Count Tilly and Gustavus Adolphus of Sweden. Tilly lost when Gustavus forced the Lech River under the cover of his artillery. Tilly was fatally injured, and carried off the field. His second-in-command, Johann von Aldringer briefly took control, but was knocked unconcious. Finally, Maximilian I, Elector of Bavaria personally ordered a retreat.
