Unbroken — Marshall Islands
Zamperini is taken to Kwajalein — known among Allied prisoners as 'Execution Island' — before transfer to Japan.
Kwajalein was a major Japanese naval and air base. Allied POWs held there were used for medical experiments and subjected to severe beatings. The island was captured by US forces in February 1944 — one of the fastest captures of a heavily fortified island in the Pacific War.
