sentences:  Between 15 May up until 5 June, under constant harassment and skirmishes, troops of the 127th Infantry Regiment decided to retreat first to Babiang which they had occupied five days before, only to be beaten back, driving them to flee to Nyaparake and Parakovio (the HQs of the Nyaparake Force), which turned out to be impossible to hold as well, and from which they had to depart on 24 May.Eventually, they made a last attempt at delaying the Japanese at Yakumol on 4 June, before being compelled to retreat by sea the following night under constant artillery shelling, relocating on a defensive line along the west bank of the Driniumor River.Several hundred Japanese and dozens of Americans died during those actions.
