Chickadee cleared Naval Station Charleston, South Carolina, on 7 April for Milford Haven, Wales, arriving there on 12 May.

She performed her hazardous duties under enemy shore fire on several occasions, but escaped with only minor damage from shrapnel and no casualties.

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.

During October and November 1944, Chickadee carried out a visual search for mines south of Sanremo, Italy, temporarily becoming the flagship of COMINRON SEVEN.

After a lengthy overhaul, Chickadee sailed from Norfolk on 18 September 1945 for the Pacific, reaching San Pedro, California, on 10 October.
