Then Enemy Underground (S01E04)

Following a rocky beginning, Admiral Chester Nimitz's island-hopping strategy in the Central Pacific has picked up steam, bringing his forces to their most significant objective: Saipan in the Mariana Islands. The intense battle that unfolded over nearly a month included fierce mountain sieges, Banzai charges, nerve-wracking dogfights, and rising friction between the U.S. Army and Marines. Vivid combat footage and firsthand accounts from the soldiers who fought there vividly capture this pivotal chapter of the Pacific War.
