an extensive 2007 survey of the hull of the wreck by divers proved there was only one). Turning at maximum revolutions, the shaft twisted and ruptured the glands that prevented sea water entering the ship via the broad shaft tunnel's interior bulkheads. The flagship promptly took in 2,400 tons of water and her speed dropped to 16 kts (30 km/h, 18 mph). Testimony from Lt Wildish, in command of 'B' Engine Room, indicated the shaft was stopped but upon restarting the shaft, water rushed in through the damaged shaft passage, flooding B Engine Room and forcing its evacuation. Also flooded from this hit were the long shaft passage itself, 'Y' Action Machinery Room, the port Diesel Dynamo Room, 'Y' Boiler Room, the Central Auxiliary Machinery Room, and a number of other compartments aft. The torpedo hit had devastating further effects. First, it caused an 11.5-degree list to port, resulting in the starboard 5.25-inch anti-aircraft turrets being unable to depress far enough to engage low-level attackers. Furthermore, power to Prince of Wales aft 5.25 inch dual-purpose turrets was cut, leaving her unable to effectively counter further attacks. Power loss to her pumps meant an inability to pump out the in-rushing flood water faster than it was entering the breached hull. The torpedo damage also denied her much of her auxiliary electrical power, vital for internal communications, ventilation, steering gear, and pumps, and for training and elevation of the 5.25-inch and 2-pounder gun mounts. All but S1 and S2 5.25 inch turrets were almost unmanageable, a factor compounded by the list, rendering their crews unable even to drag them around manually using chains. The crews also had difficulty bringing the heavy 2-pounder mountings into manual operation. The extensive internal flooding and shaft damage caused the shutting down of the inboard port propeller shaft, leaving the ship under the power of only the starboard engines and able to make just 15 knots at best. With her electric steering unresponsive, the ship was virtually unmanageable. Another torpedo attack was carried out by 26 Betty bombers of the Kanoya Air Group at approximately 12:20, and Prince of Wales was hit by another three torpedoes on her starboard side (some historical accounts state four hits, but the 2007 survey of the hull showed there had been only three); one at the very bow, one opposite B main gun turret, and one abaft Y turret which not
