"Chickadee" continued to operate off the coast of France, with frequent visits to British ports, until 1 August 1944 when she departed Plymouth, England, for Naples, Italy. After arriving in Italian waters on 12 August, she swept in the Strait of Bonifacio until 23 August when she sailed to Cavalaire Bay, France, for sweeping operations during Operation Dragoon, the invasion of southern France. Between 29 August and 2 October, she swept the harbor of Marseilles, and conducted anti-submarine patrols off that port.
