During and immediately following World War II, each major office and command in the Navy prepared an administrative history for the war period. In addition to the histories themselves, many commands submitted documentary appendices. The appendices included copies of key official records, reports, and administrative histories of subordinate commands and offices. A group of related post World War II administrative histories, mostly dating from 1945 to 1948, is included in the Post 1946 Command File. The official correspondence series includes various unit and individual ship citations and Ainsworth's permanent appointment to Rear Admiral.
All correspondence is arranged in chronological order.
In the narratives series is a description by Ainsworth of the Solomon Islands campaign and a copy of his biography. The papers contained in this collection consist of personal correspondence and notes from interviews that Commander Alden, a submarine officer, conducted for his book, The Fleet Submarine in the U.S. Navy , published by the Naval Institute Press. The collection is arranged in two series. Series I, official and personal correspondence, includes correspondence with various individuals concerning the development of the fleet-type submarine. It is arranged alphabetically by correspondent.
