Siege of Hamburg ends with French capitulation

Background. The siege occurred from December 1813 to May 1814, at the end of the War of the Sixth Coalition. Marshal Davout's 13th Corps withdrew to the Hamburg region after the defeat of Marshal Oudinot at Grossbeeren. The French had fortified the area during the summer, and the garrison played a secondary role in the German campaign of 1813.

Strategic Impact. Supplying German fortresses like Hamburg led to severe shortages of military matériel for the Napoleonic army during the Campaign of France, which began in January 1814. These garrisons tied down large numbers of Allied troops for siege operations, but their absence was felt in 1814 when the French field army was extremely reduced.

Coalition Context. The War of the Sixth Coalition saw a coalition of Austria, Prussia, Russia, and other states defeat the First French Empire. The Allies overcame French armies, occupied Paris, and forced Napoleon's first abdication in April 1814, codified in the Treaty of Fontainbleau. This context frames the end of the siege.
