home badly damaged, Hutchins believed the target to be sunk, and signalled Card: "Scratch one pig boat; am searching for more." Borie then got another radar contact about from the first, at 0153 hours on 1 November 1943, range and charged in to engage. At radar contact was lost, but sonar picked up the enemy sub at about the same time. Borie engaged (a Type VIIC U-boat) hours before dawn, at 49°00' N., 31°14' W. There were seas, with high winds and poor visibility. The destroyer initially launched depth charges, after which the submarine came (or was probably forced) to the surface. Borie then came about for another attack, engaging with 4-inch and 20 mm gunfire at a range of . The sub's six 20mm autocannons scored hits in the forward engine room and several scattered and harmless hits near the bridge, and her deck gun crew traversed their gun and took aim for their first shot at Bories waterline; but Bories 20 mm gunfire killed every exposed member of the sub's crew topside, and a salvo of three 4-inch shells then blew off the sub's deck gun before it fired a round. Borie then closed in and rammed U-405, but at the last moment, the submarine turned hard to port and a huge wave lifted the Bories bow onto the foredeck of the U-boat. After the ramming, Borie was high-centered on top of U-405, and until they separated, exchanges of small arms fire took place. This was a unique battle: unlike most other modern naval battles, it was decided by ramming and small arms fire at close range. Bories 24-inch spotlight kept the submarine illuminated throughout the following battle, except for brief periods when it was turned off for tactical reasons. The two ships were initially almost perpendicular to one another; as the battle progressed, wave action and the efforts of both crews to dislodge from the enemy ship resulted in the two vessels becoming locked in a "V" for an extended fight, with the U-boat along Bories port side. The two ships were locked together only 25–30° from parallel. The action of the seas began to open seams in Bories hull forward and flood her forward engine room. The submarine's hull, made of thicker steel and sturdier beams to withstand deep diving, was better able to handle the stress. Hutchins reported later, "We were impressed by the ruggedness
