"After locating an ancestor in the Civil War Pension Index, researchers are urged to request a copy of the casefile referred to by the index.
According to the National Archives, "...the number and type of documents in the Civil War and later series vary greatly from file to file; they are often numerous. The documents of greatest genealogical interest include the declaration of the veteran, the declaration of the widow, the statement of service from the War or Navy Department, the personal history questionnaire, and documents relating to the termination of pensions."

Photocopies of casefile contents are currently requested by submitting NATF Form 85 to the National Archives and Records Administration, Attn: NWCTB, 700 Pennsylvania Avenue, NW, Washington, D.C. 20408-0001. You can request NATF Form 85 by submitting your name and postal address, the form number (NATF Form 85), and the number of forms you require (limit 6 per request) to inquire@nara.gov."
