Joseph Bonaparte
When Napoleon took power, Lamarque served in the Napoleonic army. He fought at the Battle of Austerlitz. He then followed Marshal Masséna to support Joseph Bonaparte in Italy, and he participated in the siege of Gaeta. Joseph Bonaparte appointed Lamarque his Chief of Staff in 1807, with the rank of major general. When Joachim Murat took over from Joseph Bonaparte, Lamarque was sent to consolidate his position by capturing Capri from the British commanded by Hudson Lowe. In a bold attack, Lamarque took the British by surprise. After a hard-fought battle he succeeded in taking the island.
