MC GROGAN’S US NAVY SS-207 USS GRAMPUS PATCH "LOST BOAT" After starting on the 9th and being ordered to return on the 10th, GRAMPUS (Lt. Cmdr. J. R. Craig) departed Brisbane on 11 February to make her sixth patrol in the Solomon area, having made two successful previous patrols under Craig. After leaving her exercise target on 12 February 1943, she never was heard from again. She was directed, during the period from 14 February to 20 February, to patrol successively the area west of Shortland and south of latitude 6-30 ‘S, the entire Buka-Shortland-Rabaul Sea area, and to leave the southern part to TRITON, which subsequently was lost in this general area. On 20 February, GRAMPUS was ordered to patrol north of 4-30 ‘S, until dawn on 21 February, and then to patrol east of Buka and Bouganville. On 2 March she was told to round Cape Henpan, proceed down the west coast of Bouganville, south of Treasury Island, north of Vella Lavella and into Vella Gulf on the afternoon of 5 March. She was to sink enemy ships trying to pass westward through Blackett Strait in attempting to escape our surface ships scheduled to bombard Vila and Stanmore airstrip on 6 March. GRAYBACK was teamed with GRAMPUS in the above operation, and each was informed of the other’s assignment. The evening of 5 March, GRAYBACK and GRAMPUS were warned that two destroyers were proceeding from Faisi (off southeastern Bouganville) toward Wilson Strait (between Vella Lavella and Ganogga). These destroyers later went through Blackett Strait into Kula Gulf, where they sere sunk by our surface forces, but GRAYBACK did not report having seen or heard them. Shortly after the report concerning these destroyers was sent, GRAYBACK heard and saw a ship in the part of Vella Gulf assigned to GRAMPUS, and, assuming it was she, maneuvered to avoid. She was unable to track it or exchange recognition signals by radar, since her SJ radar was not functioning. When GRAMPUS made no radio transmission up to 67 March, she was ordered by ComTaskFor 72 on 7 March to do so. No transmission was received, and on 8 March she was ordered again to make one, again without results. She was reported lost on 22 March, 1943. Since the war’s end, the following facts have been culled from enemy sources. On 17 February 1943, the enemy claims to have sighted one of our submarines southeast. During the afternoon of the 18th, a submarine torpedo attack was delivered on enemy ships and a freighter of 6,400 tons was damaged. An enemy counter-attack was made. All of these positions were in GRAMPUS’ area. On the afternoon of 19 February, enemy seaplanes claim to have sighted and attacked a U. S. submarine somewhere southeast. The next day, two patrol boats found a large amount of oil on the surface in this position, and the enemy believed that the submarine had been sunk. However, another enemy report states that a submarine was sighted on 24 February in the southeast. Since no other U.S. submarine could have been in this position at this time, it may be assumed that GRAMPUS escaped serious injury on 19 February, or that AMBERJACK was the victim of the attack of 19 February. Whether the shop GRAYBACK saw and heard in Vella Gulf on the night of 5-6 March 1943 was GRAMPUS is impossible to determine, since she was unable to identify it. However, if it was GRAMPUS and she did survive the enemy attack of 19 February, the only other possibility, so far is now known, is that GRAMPUS was sunk by the destroyers passing through Blackett Strait on the night of 5-6 March, 1943. From the information at hand, it appears that GRAMPUS could have been no more than 15 miles from GRAYBACK on that night, yet GRAYBACK reported hearing no depth charges. In view of this, it seems likely that GRAMPUS was caught on the surface by the destroyers and sunk by gunfire. Since the enemy ships were themselves destroyed subsequently, no mention of any attack by them is made in Japanese reports. A large oil slick was reported in Blackett Strait on 6 March. In the five patrols made before her fatal one, this ship sank six ships, for a total of 45,000 tons, and damaged two more, for 3,000 tons. On her first patrol, conducted in February and March 1942 in the Caroline Islands, GRAMPUS sand two 10,000-ton tankers and reconnoitered Wotje and Kwajalein atolls. Her second patrol was a passage from Pearl Harbor to Fremantle, Western Australia, and no sinkings were made. Going to the area west of Luzon and Mindoro, P.I., for her third patrol, GRAMPUS was again unsuccessful in her attempts to sink enemy ships. She conducted her fourth patrol in the Solomons. Here she landed coast watchers on Vella Lavella and Choiseul Islands, and was credited with one escort type vessel sunk and another damaged. GRAMPUS’ fifth patrol was made in the Solomons also. She sank a large transport, a medium transport, a freighter and damaged a destroyer.
