Acting on this information, the division ordered the 163d to send all available units southward to block escape routes but not to attack. K Company had remained just east of the road since the 12th, and B Company was sent from Huggins down the west side. These 2 companies moved south astride the road, and on the Killerton trail E and G Companies, after too rounds from the artillery and 200 from their 81-mm mortars, also moved southward. Nearly 100 Japanese were killed by this bombardment and by the infantry when it followed up. Meanwhile, the 18th Brigade renewed its attack and completely broke enemy resistance south of Huggins. For more than a mile north of its junction with the Soputa–Sanananda Road the Killerton trail was open. The first phase of the divisional plan of attack was now completed.
At 0730 on the morning of the 15th, a platoon of A Company, attacking from "Q," managed to get inside Perimeter "R" from the north without being detected. The rest of the company was at once pushed in. C Company, operating from Fisk, sent a platoon to press from the east. B, E, G, and K Companies were now released by the 7th Division from their southward movement and B was sent to the west side of "R" to complete the encirclement. Bunker after bunker was taken in attacks by small groups of our men using grenades, rifles, and submachine guns, but the entire perimeter was not captured until the following day. Shortly before noon, General Vasey came to Huggins and explained the plan for a second phase of the attack to begin next day.

The 18th Brigade, leaving the remnant of the enemy south of Huggins to be mopped up by reserve elements, was to move up the Killerton trail through the 2d Battalion of the 163d and carry out the envelopment of Sanananda. The 2d Battalion of the 163d was to cooperate by moving north from Rankin about 1½ miles along the Killerton trail to the Coconut Garden, where a branch trail connecting with the Soputa–Sanananda Road was believed to come in. After the Australian advance, the battalion would follow the branch trail east to the road, taking in the rear the enemy positions north of Huggins. The 3d Battalion, operating from Huggins and Fisk, was scheduled to complete the reduction of Perimeter "R." The 1st Bat-
