Sinking
After arriving in the area the Block Island picked up a radar contact which turned out to be veteran German submarine U-66 which had sunk over 200,000 tons of Allied shipping in its three years of attack patrols. Captain Seehausen of the U-66 successfully evaded the Block Island task group for several days. On 5 May 1944 the Block Island picked up the sub only 5,000 yards off starboard, maneuvering for an attack on the carrier. The Block Island made an emergency turn at flank speed with Captain Hughes sending the Buckley to investigate.
Only a few hours later at 0330 on 6 May 1944, pilot Jimmie Sellars, with a nickname of “Geronimo”, flying a stripped-down TBM, followed up a radar contact and found U-66 on the surface in bright moonlight. Captain Seehausen kept U-66 on the surface, reporting to Brest, France while keeping the TBM at a distance by firing AA. Sellars stayed on station until the Buckley could attack. At one point he dived his unarmed TBM directly at the sub emptying his Colt 45 into the conning tower!

Block Island remained in the area with the captured Germans until 13 May 1944 when relieved by CVE 9 Bogue. CVE 21 reached Casablanca 18 May 1944. The re-supplied carrier was again underway on 23 May 1944 and back in the vicinity of the Cape Verde Islands. On 28 May 1944 the Block Island’s search TBMs picked up a radar contact and then lost it. It was U-549, a 750 ton type IXc U-Boat on its very first patrol. Another contact was made at 0255 on 29 May 1944 but it disappeared before ordinance could be dropped. As Block Island continued its search over the next hours the U-Boat continued to evade the hunter.


With the Block Island’s fate now sealed, Captain Hughes gave the order to abandon ship starting from the forward starboard side. Life rafts were cut loose and even some rafts on TBMs were thrown into the water. Most men descended down ropes into the water from the starboard or lee side so they could drift way from the ship. By 2100 most of the crew were in the water and began gathering around rafts.
Captain Hughes kept a small group on board including men who were trying to free a man whose leg was trapped. After an hour of using an acetylene torch to no avail, the ship’s surgeon removed the leg only to have the man die a short time later. Six other men who had lost their lives remained on board. Captain Hughes ordered all remaining personnel off CVE 21 at 2140.
DE 575 Ahrens stopped engines and began picking up survivors. With its engines quiet it picked up sonar noise from U-549. Captain Harris of the Ahrens radioed the Eugene E. Elmore immediately. Hedgehogs (ant-submarine mortars) from DE 686 Eugene E. Elmore struck U-549 at 2127 causing a large explosion audible to ships monitoring in the area and sending the sub crew to the bottom of the sea. The Robert I. Paine picked up additional survivors as the Block Island began to sink. At 2155 the Block Island slipped below the surface followed by a large shock as ordnance magazines exploded. The Ahrens was nearly lifted from the sea as a result and many of the CVE 21 survivors thought they had been torpedoed.
Several crewmen of CVE 21 remember that at the time the submarine was spotted some of the Block Island gun crews were still at their battle stations. Word was passed for the 5” gun on the fantail to train on the area where the periscope was
spotted. This gun crew answered that it was impossible for them to train on the periscope because the carrier
was so low in the water that any shots they could take would strike the underside of the flight deck. The orders
then were for the gun crew to abandon ship as ordered.
Everyone who went over the side of the Block Island into the sea survived, a total 674 men crowded every space on the Ahrens and 277 were crammed aboard the Paine. Unfortunately, of the six pilots in the air at the time of the sinking only two were able to reach Las Palmas, the other four were never found.
