[1] Shortly after the outbreak of the war, the Junta de Asturias promoted Worster to lieutenant general and at the beginning of 1809 he was given command of the 5th Division, responsible for defending the line of the river Eo, which forms the boundary between Galicia and Asturias, and liaising with the Army of Galicia.
Marquis de La Romana, commander-in-chief of the Army of the Left, ordered him to march towards Oviedo,[2] but when Worster heard that Marshal Ney was approaching Castropol, with vastly superior forces, the Spanish troops were able to escape up into the mountains.
[1] After Worster had complained directly to Wellington (4 September 1812), the governor, Francisco Dionisio Vives, and the second-in-command of Old Castille, Carlos de España, both accused him of insubordination, for which he was arrested and relieved of his command.
On 1 October 1814, the secretary for War published the decree in which Ferdinand VII fully absolved him and he was reinstated in his post at Ciudad Rodrigo.
[1] In December 1815, Worster was appointed commander of Artillery at Vigo, post he held until October the following year, when he was transferred to the barracks at Toro.
