Once war began again between Britain and France in 1805, Yeo became first lieutenant of the frigate . The frigate was patrolling off the northwest coast of Spain when "Loire"s commanding officer, Captain F.L. Maitland, chose to attack shipping in Muros Bay, Spain. Lieutenant Yeo led fifty men ashore to attack a shore battery that was firing on the frigate. Once there, they found a second, more powerful emplacement and captured that one too. During the battle, Yeo was stabbed with a bayonet. The Spanish suffered over forty casualties in the engagement, the British six. "Loire" captured three vessels at Muros Bay including the 22-gun corvette . As a reward, he was promoted to commander on 21 June and given the command of the captured "Confiance", which had been taken into Royal Navy service.
