Angaur (134.14E 6.90N) is a small island in the Palau group. It is mostly flat and was mined for small quantities of phosphate. The Japanese built a secondary military airfield here to support the main airfield at Peleliu.
Elements of 81 Division invaded the island on the
15 September 1944, at the same time that nearby Peleliu was invaded.
The island was overrun relatively quickly, and 81 Division was
redeployed to Peleliu, where the Marines
had run into considerable difficulty.
