The Battle of Stockach and Engen was fought on 3 May 1800 between the army of the First French Republic under Jean Victor Marie Moreau and the army of Habsburg Austria led by Pál Kray. The fighting near Engen resulted in a stalemate with heavy losses on both sides. However, while the two main armies were engaged at Engen, Claude Lecourbe captured Stockach from its Austrian defenders under the Joseph, Prince of Lorraine-Vaudemont. The loss of his main supply base at Stockach compelled Kray to order a retreat. Stockach is located near the northwestern end of Lake Constance while Engen is west of Stockach. The action occurred during the War of the Second Coalition, part of the French Revolutionary Wars.
