6738. Our 5394.1 After consultation with Captain Mulleneaux|2| Department approves Admiralty’s plan of routing in principle as follows:

     East-bound ships to follow lanes as far as Longitude 47 degrees, 1 lane for Halifax, 1 for New York and 1 for Hampton Roads, Virginia. New York and Hampton Roads lanes to be regarded as available for Eastward Ships from either port thus giving in effect a Northern and a Southern Route. Lanes 60 miles wide allow for slight difference between successive convoy tracks. All other waters to be available for Westbound ships, Eastbound lanes to be crossed only during daylight.

     Lanes approaching routes to be used for each principal port with Code similar to system in use abroad. Details will be cabled shortly. Cancel Department’s plan forwarded by cable and mail. Inform Admiralty. 11001. 6738
