alleged an early resumption of the offensive. Extensive smoke screens rose north of the 38th Parallel ahead of IX Corps and above the Hwacheon Reservoir in the X Corps' sector. Drawing Van Fleet's particular notice were reports that five PVA armies, the 60th, 15th, 12th, 27th and 20th, were massing west of the Pukhan for a major attack in the west central sector. In further instructions for defense, Van Fleet ordered the No-Name Line fortifications improved and directed General Hoge to give special attention to the Pukhan corridor, where the heaviest enemy buildup was reported. Hoge was to place the bulk of IX Corps' artillery on that flank. "I want to stop the Chinese here and hurt him," Van Fleet told Hoge. "I welcome his attack and want to be strong enough in position and fire power to defeat him." Lavish artillery fire, in particular, was to be used. If gun positions could be kept supplied with ammunition, Van Fleet wanted five times the normal day of fire expended against enemy attacks. As calculated by his G-4, Colonel Stebbins, the "Van Fleet day of fire" could be supported for at least seven days, although transportation could become a problem since Stebbins could not haul other supplies while handling that amount of ammunition. Rations and petroleum products already stocked in Corps' sectors, however, would last for more than seven days. Immediate army reserves for the advance to the Topeka Line were to have been the 3rd Division, to be withdrawn from I Corps, and the Canadian 25th Infantry Brigade, which had reached Korea on 5 May. Having undergone extensive training at Fort Lewis, Washington, the brigade would be ready to join operations after brief tune-up exercises in the Pusan area. Though the Topeka advance was off, Van Fleet ordered the Canadians to move north, beginning on 15 May, to Kumnyangjang-ni, southeast of Seoul, and prepare to counter any enemy penetration in the Pukhan or Seoul-Suwon corridors. The 3rd Division was still to pass to army reserve and organize forces capable of reinforcing or counterattacking in the I, IX or X Corps sectors in at least regimental combat team strength on six hours’ notice. Beginning on the 11th, the 15th Regimental Combat Team assembled near Ich’on, at the intersection of Routes 13 and 20 southeast of Seoul, ready to move on call into the X Corps' sector; for operations in support of
