Jarmin Pass proved to be a difficult objective for the Americans, but once Moore Ridge had been taken, US troops were able to attack the Japanese holding the Pass from both north and south. Although the US troops of the 7th Infantry Division were up before the sun on May 17, 1943, they did not take fire from the Japanese 303rd Independent Infantry Battalion until 0530 hours when units on the south track saw mortar fire from the southwest hill. At 0600, units on the central track were fired on by a machine gun nest on the east ridge. Both the Japanese infantry on the southwest hill and the HMG nest near the central track were neutralized by 0800, and the Japanese Captain in charge of the battle lost his life when the mortar installation on the southwest hill was destroyed at 0845. However, during that time, hidden Japanese units had been moving toward the north end of the track from both east and west under the cover of heavy fog. Despite being under assault, an HMG platoon in the west and 2 infantry platoons in the east were able to keep the track within their firing range impeding American troop movement through the pass.

The primary objective of this scenario is to have a clear track that is free of Japanese units and out of their direct fire range. Step losses play a role in secondary victory determination. This is another scenario where the Japanese player can hold back a few hidden units and make a run for the track later in the scenario in the hope of preventing US control. Japanese units were placed on both western hills and the east ridge with that intention. The Americans expanded their perimeter aligned on both sides of the track in an effort to identify those units before they could compromise the secure perimeter. In the end, although the three Japanese units noted above were under assault, they had the track within their direct firing range and were undemoralized, so they fulfilled one of the primary criteria. However, because the American only lost four steps to the Japanese total of seven steps loss, the scenario ended in a draw.
