Battle of Kulm
Summary
Vandamme, sent in pursuit of the Allies after Dresden, advanced too far without support. He was caught in a pincer by superior forces from the rear and flank. His corps was nearly annihilated and he himself was captured. This defeat canceled the tactical benefits of Dresden.
Historical context
Napoleon ordered pursuit of coalition armies after their retreat from Dresden. Vandamme crossed the Bohemian passes without coordination with other corps. The Allies took advantage of his isolation to trap him at Kulm.
Tactics
The Allies launched a frontal attack while Prussian reinforcements took Vandamme in reverse. Trapped in a enclosed valley, the French fought to exhaustion without escape. Surrender became inevitable.
Consequences
The destruction of Vandamme's corps ruined Napoleon's strategic momentum in Saxony. It marked the beginning of a series of reverses leading to Leipzig. The failure at Kulm shocked the French general staff.
