At 2137, U.S.S. WILSON DD-408 in station No. 7 reported sound contact while task group was on ZZ leg 190 Degrees; Emergency Six-Turn executed immediately, putting SIGSBEE ahead of task group. 2140 this vessel made sound contact bearing 125 Degrees T distance 750 yards.
Dropped a two charge barrage. Lost contact shortly there-after. Proceeding independently searching for submarine. 2204 regained contact bearing 280 degrees T, 650 yards. 2206 obtained fathometer reading of 180 feet. Dropped two depth charges. Data not sufficient for a full charge destructive pattern. 2214 regained contact bearing 115 degrees T, 2000 yards. Data very good and made a very good run, firing an 11 charge pattern , medium depth setting, at 2218. Continued search until 2330. Departed from area in company with U.S.S. Wilson DD-408 to rejoin task group in accordance with CTG 50.8 orders to rejoin if contact not regained within one hour. During search no evidence was noted. Classify this contact as possible submarine.
