Eleven rounds were fired at this barge before fire was shifted to the first barge. After three hits she caught fire and sank rapidly. Since the other barges were still afloat P 43 turned an opened fire on the other barges again. The last barge of the line soon rolled over and sank.

There was now not enough time left to do a full patrol and it was decided that Unison would run A/S exercises for destroyers based on Malta. She did so for three days while awaiting her passage to the U.K. This included an exercise with HMS Wheatland (Lt.Cdr. R. de L. Brooke, DSO, DSC and Bar, RN) using Pillenwerfer seized on the Italian submarine Bronzo. (9)
