The ground forces would be supported by two naval bombardment forces. Task Force 74, under British Rear Admiral Victor Crutchley, consisted of the cruisers HMAS "Australia" and "Shropshire" plus several destroyers, while Task Force 75 was made up of three U.S. cruisers, "Phoenix", "Nashville" and "Boise" under Rear Admiral Russell Berkey. These were supported by a force of eight escort carriers of the 5th Fleet. Secondary landings would take place Aitape, 125 miles to the east, at the same time as those around Hollandia. The decision to undertake these operations simultaneously stretched Allied shipping and logistics resources, and necessitated reallocating resources from other theaters and roles. The shortage of shipping meant that each ship had to be loaded as efficiently as possible, using a technique known as combat loading to ensure that the most important stores and equipment could be unloaded quickly.
