unaware that a large force of Japanese land-based bombers were looking for his ships, but, not having anticipated his detour to Kuantan, were searching much farther south. At around 10:00 Tenedos, having been detached from the main force the previous day and now about 140 miles southeast of Force Z, began signalling she was being attacked by Japanese aircraft. The attack was carried out by nine Mitsubishi G3M 'Nell' twin-engine medium bombers from the Genzan Air Corps, 22nd Air Flotilla, based at Saigon, each armed with one 500 kg (1,100 lb) armour-piercing bomb. They mistook the destroyer for a battleship and wasted their ordnance without scoring a hit. At 10:15, a scout plane to the north of most of the Japanese aircraft piloted by Ensign Masato Hoashi spotted Force Z and sent out a message detailing their exact position. The remaining Japanese planes converged upon the retreating British task force. The planes had spread out to search for the British warships, so they arrived over the target in small groups. With fuel running short, the Japanese attacked as they arrived rather than forming into a large force for a co-ordinated strike. The first wave of Japanese planes, comprising eight Nell bombers from the Mihoro Air Corps, attacked at 11:13, concentrating solely on Repulse. Besides seven near misses by 250 kg (550 lb) bombs, they scored just one hit, which penetrated the hangar and the upper deck and exploded in the marine mess area. The bomb caused no serious damage and relatively few casualties, and Repulse continued on at 25 kts (46 km/h, 29 mph), still in fighting trim. Five of the eight bombers were damaged by anti-aircraft fire, and two were forced to return to base. At around 1140, 17 Nell torpedo bombers (two squadrons from the Genzan Air Group) approached the two capital ships. Eight concentrated on Repulse, while nine attacked Prince of Wales, sending eight torpedoes speeding towards the flagship (one plane aborted its run on Prince of Wales and peeled off and attacked Repulse). One Nell was shot down and three more were damaged by the Prince of Wales anti-aircraft fire during this attack. This first wave of torpedo attackers made no hits on Repulse but managed one ultimately fatal hit on Prince of Wales, right where her outer port propeller shaft exited the hull (some historical accounts state there were two hits in this attack, but
