Input: Consider Input: Question: Who fought in the battle that ended with the 5th securing the area in April of 1944? Passage:This plan was short-lived, and on 23 August 1943, the divisional headquarters, under Milford moved to the north coast of New Guinea, to take over the Salamaua campaign in its final stages. Landing at Nassau Bay, the headquarters took over from the 3rd Division and assumed control of its subordinate troops: the Australian 15th, 17th and 29th Brigades, and the US 162nd Infantry Regiment. The division occupied Salamaua on 11 September. After this, the division moved to Lae, which had been captured by the 7th Division, and between September 1943 and February 1944, its headquarters assumed the designation of HQ Lae Fortress, as the area was developed as a base for further operations around the Huon Peninsula and in the Ramu Valley. The division also undertook mopping up operations, securing small pockets of Japanese defenders left behind. By this time, the division reported to II Corps, and had adopted the jungle divisional establishment. After being re-designated once again as the 5th Division, the headquarters moved to Finschafen, assuming control of the 4th and 8th Brigades, and taking over the advance along the Rai coast towards Madang, which was secured in April 1944. Throughout the coming months, the 15th Brigade was reassigned to the division, as was the 7th Brigade, although both the 15th and 4th Brigades were returned to Australia in July and August 1944.

To go south, the traveler would follow the Green River. The Union Pass Route was an extension of a North South Route up the Valley of the Yellowstone. Coming up the Valley of the Thoroughfare, west of the Absaroka Mountains and south of Yellowstone Lake, the trail followed the North Fork of the Yellowstone. Crossing over Two Ocean Pass, the trail split east and west around Terrace Mountain into the Wind River Valley at DuNoir. From Union Pass south bound travelers could use the Green River Valley to connect east through South Pass or west toward the Snake River.
