This series consists of card indexes of the Judge Advocate General's Office, Military Deputy's Department relating to war crimes in Europe during Second World War. The indexes were compiled c1944 to 1948.

The series comprises six card indexes:

• an accused index (alphabetical);
• a witness index (alphabetical);
• a dead victims index (alphabetical);
• a placenames index (alphabetical);
• a numerical index of camps; and
• a numerical index to the Judge Advocate General, Military Deputy FS files.

All the indexes carry FS references (with or without prefix) which refer to files in WO 311. The numerical index in pieces 23 and 24 contains those cards from which the Director of Army Legal Services (DALS) compiled its MD/JAG inventory, on which, in turn, the WO 311 list is based.

Some index cards in pieces 23 and 24 constitute partial indexes to TS 26/174-802 and WO 309. These cards are marked with the following information which is valuable for cross-reference:

• (1) Many cards in pieces 23 and 24 bear UK G/B number references, which are Charge Numbers quoted in TS 26 cases;
• (2) A block of cards under reference FS 76 in piece 24 bear BAOR 15228/C numbers (and exceptionally other BAOR references) which relate to files in WO 309.
