"Anderson" remained at Placentia Bay for almost a week before getting underway on 10 October as part of the antisubmarine screen for TF 14, formed around "Yorktown". This force reached Casco Bay, Maine, on the afternoon of 13 October. Moving down to Provincetown, "Anderson" again conducted antisubmarine exercises, and as in previous practices, the ship's performance was "outstanding in detecting the presence of a submarine and carrying out a successful attack." Later, after a tender availability alongside at Casco Bay, she resumed her operations at sea with TF 14.
