François Gédéon, comte Bailly de Monthion (French pronunciation: [fʁɑ̃swa ʒede.ɔ̃ baji də mɔ̃tjɔ̃]; 1776–1850) was a French general.
Monthion enlisted in an infantry regiment in February 1793 and saw active service at Marengo (1800) and Austerlitz (1805).
[1] On 20 September 1808, Monthion's troops were routed at Bilbao by Blake, who had previously set in motion a plan to threaten Burgos with a small portion of his army of some 32,000 Galicians and Asturians, while with the main body he would march on Bilbao.
[2] Having sent his 'vanguard' and 'reserve' brigades towards Burgos, Blake moved on Bilbao with four complete divisions, with the Marquis of Portazgo's division routing the 1,500-strong French garrison, and Monthion withdrawing to Durango.
In July 1811, General Monthion's Reserve of the Army of Spain, stationed at Bayonne, numbered 8,047 men, with 251 officers.
