"Anderson" then visited San Juan, Puerto Rico (from 1–5 August); Coco Solo, Panama Canal Zone (8–14 August); and Hamilton, Bermuda (19–21 August); St. John's, Newfoundland (25–28 August); before she reached Montreal, Quebec, Canada, on the morning of 31 August. Underway on 5 September, the destroyer called briefly at Quebec (5 to 6 September) before she headed for Newport. On 8 September, while en route, "Anderson" sighted a merchantman eight miles (13 km) distant, identifying her as Norwegian by the display of national colors on ship's side. Soon thereafter, a plane, identified as "British" (possibly Royal Canadian Air Force) by the wing markings, circled "Anderson" at low altitude, obviously scrutinizing the ship thoroughly before banking away and heading for the coast.
