Other forces under Kinkaid's command included the cruisers of Task Force 74 under Rear Admiral Victor Crutchley, Task Force 75 under Russell S. Berkey, and Task Force 76, the VII Amphibious Force, under Rear Admiral Daniel E. Barbey. The main role of the Seventh Fleet was supporting MacArthur's drive along the northern coast of New Guinea with a series of 38 amphibious operations, usually directed by Barbey. Kinkaid accompanied MacArthur for the landing in the Admiralty Islands, where the two men came ashore a few hours after the assault troops. With 215 vessels involved, Operations Reckless and Persecution in April 1944 together constituted the largest operation in New Guinea waters. It was followed in quick succession by four more operations, at Wakde, Biak, Noemfor and Sansapor.
