and 246 taken captive. This report included information obtained daily from UN ground units only. At UN headquarters in Tokyo, the estimate was that enemy forces suffered between 75,000 and 80,000 killed and wounded, 50,000 of these in the Seoul sector. Other estimates listed 71,712 enemy casualties on the I Corps' front and 8,009 in the IX Corps sector. Although none of the estimates was certifiable, PVA/KPA losses were unquestionably huge. Notwithstanding the high enemy losses, General Van Fleet cautioned on 1 May that the enemy had the men to "Attack again as hard as before or harder." The total strength of PVA forces in Korea as of that date was believed to be about 542,000 and that of KPA forces to be over 197,000. The 1 May estimate in General Ridgway's headquarters credited the PVA/KPA with having 300,000 men currently in position to attack, most of these on the central front. Interregnum (1–14 May) Intent on confronting PVA/KPA forces with the most formidable defenses yet, General Van Fleet on 30 April ordered the length of the No-Name Line fortified like its Golden Line segment around Seoul. Fortifications were to include log and sandbag bunkers, multiple bands of barbed wire with antipersonnel mines interspersed, and 55-gallon drums of Napalm mixed with gasoline set out in front of defensive positions and rigged for detonation from the bunkers. Van Fleet also wanted provision made for counterattacking quickly once the enemy had been turned back. Van Fleet expected the PVA/KPA's next principal effort to come either in the west, as had the main force of the April attacks, or on his central front. Judging the Uijeongbu-Seoul, Pukhan River and Chuncheon-Hongcheon corridors to be the most likely axes of advance, he shifted forces by 4 May to place most of his strength and all US divisions in the western and central sectors and aligned I, IX and X Corps so that each was responsible for one of these avenues. Deployed around Seoul, I Corps blocked the Uijeongbu approach with the ROK 1st, 1st Cavalry, and 25th Divisions on line and the 3rd Division and British 29th Brigade in reserve. IX Corps, its sector narrowed by a westward shift of its right boundary, now had the British 28th Brigade, 24th Division, ROK 2d Division, ROK 6th Division and 7th Division west to east on the No-Name Line and the 187th Airborne Regimental Combat Team in
