"The Austrians counterattacked in the central Adriatic on 23 July. Cruisers, destroyers, and torpedo boats raided the Tremiti Islands and the Italian coast from Grottamare to Termoli. They repeated the attacks, joined by aircraft, somewhat farther to the north between Fano and Ancona on the 28th. The same day they made an unsuccessful attempt to recapture Pelagosa. The expedition consisted of two cruisers, six destroyers, and a number of torpedo boats, with the submarine UB.14 scouting in advance."
