Histoire du Consulat et de l'Empire, (Vol. 10 / 20) / faisant suite à l'Histoire de la Révolution Française

This work recounts the diplomatic strains and military campaigns surrounding the French return from Spain and the outbreak of war with Austria in 1809. It follows the leader's abrupt journey back to Paris, the collapse of European negotiations, Russia's ambiguous posture, and wide French preparations including expanded conscription, Guard reinforcement, and troop movements in Germany and Italy. Detailed operational narrative examines maneuvers and battles in Bavaria—Davout's difficult marches, the concentration at Abensberg, actions at Tengen, Abensberg and Eckmühl—and closes with the Austrian retreat into Bohemia and the capture of Ratisbonne, assessing military results and political repercussions.
