[3] When Joseph Bonaparte became King of Spain in 1808 Lafon-Blaniac entered Spanish service as his aide-de-camp, with the rank of major general.

[1] In March 1812, Lafon-Blaniac was named governor of La Mancha and given command of the vanguard for the Army of the Centre.

[4] At the beginning of August, with Wellington's vanguard rapidly approaching, Lafon-Blaniac was given the order to defend the citadel —contrary to Jourdan's advice[4]— rather than withdrawing from the capital.

[4] Wellington himself had entered the city two days previously;[5] an initial attack on the citadel had forced its defenders into the inner enceinte which, although formidably palisaded, with a ditch twelve feet deep and twenty-four wide, had only one well left.

After the July Revolution of 1830 he was reactivated, named a grand officer of the Legion of Honour and later given command of a division on Corsica.
