After marching around 300 kilometres from Ban Pong to up-country Thailand in early May, the Australians and British prisoners of F force were ultimately spread across at least six camps progressing toward the Burma border: Konkoita (no. 4 camp), Shimo (Lower) Ni Thea (Nieke), Shimo (Lower) Songkurai (no. 1), Songkurai (no. 2), Kami (Upper) Songkurai (no. 3) and Changaraya (no. 5). Some Australian prisoners, under Lieutenant-Colonel S.A.F. Pond, were separated from the main F Force and moved across various camps, including Taimonta and Tha Khanun. [Map source: ©2014 Google]
