Indefatigable alone lost two killed and 11 wounded. Polyphemus had two men lightly wounded. The 21 missing men were in a boat from ; a later report suggested that most, if not all, had been taken prisoner. The majority of the boats were either shot through or so badly stove in that they were swamped, and had to be cut adrift from the brig as she was brought out under fire from the batteries and the ex-British brig . The vessels claiming prize money included and the hired armed lugger Nile, in addition to the various ships of the line and frigates.

In March Murray's squadron carried troops from the Cape of Good Hope to
