Collision with British Freighter
On November 19, 1917, while about 110 miles west of Gibraltar on escort duty, Chauncey was rammed by the British merchantman SS Rose as both ships steamed in war-imposed darkness. At 0317 Chauncey sank in 1500 fathoms, taking to their death 21 men including her captain. Seventy survivors were picked up by Rose and carried to port.
