1641. Your 8546. At certain periods of month transports arrive in increased numbers and destroyers will be fully occupied providing escort transports and H B convoys. At slack periods a number of ships can be sent in H N convoys. As transport programme is known notice can be given of HN convoys that may take ships for French Atlantic ports, together with number of ships. At any time one or possibly two ships can be sent in HN convoys if necessary. No additional ships should be sent except in those convoys where specific exceptions are made. As shipping increases and new destroyers become available the limitations can be withdrawn. HN-79 and HN 80 may each bring a maximum of 10 ships. Further word will be sent re HN-81 and subsequent convoys. Admiralty concur and request C-in-C N.A. and W. I. be informed. 1641. 17523.
