Freire spent the next two years in Rousillon and Catalonia, including that war's last actions during which Spanish forces recaptured Puigcerda and Bellver (after the peace treaty had been signed).
Freire joined fellow Spaniards in fighting against invading Napoleonic forces, and on 15 September 1807, took command (as colonel) of a volunteer cavalry regiment in Madrid.
On 10 January 1810, he was appointed commander of cavalry under Juan Carlos de Aréizaga and led them at Ocaña on 19 November, a devastating defeat that cost the Spanish control of Andalusia.
At the Battle of the Bidassoa on 7 October, Freire led the divisions of Generals Del Barco and Barcena across the river to capture French positions on Mont Calvaire.
[4] He fought with "conspicuous gallantry"[5] at the Battle of Toulouse in 1814, where his two divisions were desperately mauled in the fighting for the French redoubts on Mont Rave.
