To exploit the discovery, a composite patrol from the 1st Marines, under the command of Captain Nickolai Stevenson, pushed south along that trail Slay had followed, while a composite company from the 7th Marines, under Captain Preston S. Parish, landed at Sag Sag on the west coast and advanced along the east-west track. An Australian reserve officer, William G. Wiedeman, who had been an Episcopal missionary at Sag Sag, served as Parish's guide and contact with the native populace. When determined opposition stopped Stevenson short of the trail junction near Mount Talawe, Captain George P. Hunt's Company K, 1st Marines, renewed the attack.
On 28 January, Hunt concluded he had brought the Japanese to bay and attacked. For three hours that afternoon, his Marines tried unsuccessfully to break though a line of bunkers concealed by jungle growth, losing 15 killed or wounded. When Hunt withdrew beyond reach of the Japanese mortars that had scourged his company during the action, the enemy emerged from cover and attempted to pursue, a bold but foolish move that exposed the troops to deadly fire that cleared the way for an advance to the trail junction. Hunt and Parish joined forces and probed farther, only to be stopped by a Japanese ambush. At this point, Major William J. Piper, Jr., the executive officer of the 3d Battalion, 7th Marines, assumed command, renewed the pursuit on 30 January, and discovered the enemy had fled. Shortly afterward Piper's combined patrol made contact with those dispatched inland by the 5th Marines.

Thus far, a vigorous pursuit along the coast and on the inland trails had failed to ensnare the Japanese. The Marines captured Matsuda's abandoned headquarters in the shadow of Mount Talawe and a cache of documents that the enemy buried rather than burned, perhaps because smoke would almost certainly bring air strikes or artillery fire, but the Japanese general and his troops escaped. Where had Matsuda Force gone?
Since a trail net led from the vicinity of Mount Talawe to the south, General Shepherd concluded that Matsuda was headed in that direction. The assistant division commander therefore organized a composite battalion of six reinforced rifle companies, some 3,900 officers and men in all, which General Rupertus entrusted to Lieutenant Colonel Puller. This patrol was to advance from Agulupella on the east-west track, down the so-called Government Trail all the way to Gilnit, a village on the Itni River, inland of Cape Bushing on New Britain's southern coast. Before Puller could set out, information discovered at Matsuda's former headquarters and translated revealed that the enemy actually was retreating to the northeast. As a result, Rupertus detached the recently arrived 1st Battalion, 5th Marines, and reduced Puller's force from almost 4,000 to fewer than 400, still too many to be supplied by the 150 native bearers assigned to the column for the march through the jungle to Gilnit.
During the trek, Puller's Marines depended heavily on supplies dropped from airplanes. Piper Cubs capable at best of carrying two cases of rations in addition to the pilot and observer, deposited their loads at villages along the way, and Fifth Air Force B-17s dropped cargo by the ton. Supplies delivered from the sky made the patrol possible but did little to ameliorate the discomfort of the Marines slogging through the mud.
