Does anyone know where I can find information about the Allied sieges of French positions in Germany during the 1813 war? Nearly every history book I read abruptly ends the campaign in Germany with the evacuation of the French Field army. However most of these books comment on the 100,000 French troops left behind to hold onto fortresses. As far as I know there were major sieges in Germany during this time period that had would be the equivalent of major battles. The sieges I am aware of are: Danzig (of which I have read in Rapp's memoirs), Torgau, Dresden, Mainz, and Hamburg (of which I have read some information about in the biography of Davout).
Does anyone know where I can get some info (preferably in Google Books) regarding these sieges?
