Early in 1655 Blake sent a demand to the Bey of Tunis for the the return of an English merchant ship, English prisoners, an indemnity and a future agreement, but was refused. After sailing back and forth between Sardinia, Tunis and Sicily for nearly 2 months, and sending the demands again, he arrived at Porto Farina, where the Tunisian ships were, on 13 April. His first division attacked the Tunisian ships, boarding and burning them by 8am, while his second division of larger ships attacked the forts, silencing them by 11am. After this he sailed out of the harbor. British casualties were 25 killed and 40 wounded. The Bey still refused his demands, but his attack helped the Venetians against the Muslim states.
