Regulating and routing of Atlantic trade
Folio 1: Title page.
Folio 2: Explanatory note. During the period of the War, papers of a confidential nature in the office of the C-in-C Home Fleet were filed in Packs (numbered separately from the non-confidential records) in a Series 001 to 0042 inclusive. Copies of relevant telegrams were filed in these packs, but a complete set of all telegrams was also maintained. The secret packs were re-arranged by the Grand Fleet secretarial staff in February 1919, when papers considered unimportant were removed and destroyed, and the remainder re-indexed. They were received in this form by the Historical Section in April 1920, and bound as received, in a series of Volumes. The 1919 index will be found in the first volume (see ADM 137/1881) and extracts from this have been inserted in each succeeding volume. This volume is the 19th of the series.
