    William P Biddle 106k USS Rixey (APH-3) in a floating drydock on the Wellington, N.Z., waterfront, 27 October 1943. USS William P. Biddle (APA-8), USS Harris (APA-2) and USS Sheridan (APA-51) are riding at anchor in the harbor and destroyers USS Anderson (DD-411) and USS Russell (DD-414) are nested pierside. All units are in continuing TF53 exercises and drills for the coming assault of Tarawa in November. Both destroyers were part of TF 53 that provided escort screen for the attack transports heading for Tarawa, screened heavier battle units as they shelled Betio Island in support of the landings, and provided additional fire support for the attack transports as they collected Marine casualties.

Marine reserve bugler Oscar Ackleson is in the top bunk with PFC John Martin below. Behind PFC Martin is Cpl Jimmy Comedy and below him is PFC Francis Giol. It is believed this is in one of the staterooms at the lower level of the superstructure due to the view through the portholes.
