ORDERS FOR UNITED STATES SUBMARINE CHASERS OPERATING
1. The Submarine Chasers will be used primarily for hunting submarines rather than for patrolling an area, and every effort will be made to close the known or approximate position of a submarine however this information may be obtained.
2. The regular area of operations will be between Start Point and the vicinity of the Lizard (Meridian of 5°20' W.), and each of these two points should ordinarily be covered by a Submarine Chaser Group.
3. The Groups will not cross Meridian 3°38' W. or 5°20' W, unless specially ordered or unless the hunt of a submarine carries them over.
4. As many Groups as possible will be kept at sea or in “Stand-by” status in harbour, depending upon submarine activity, weather, etc.
5. The following ports offer good refuge for Chasers, and depth charges and petrol may be obtained, except at Salcombe:-
6. It is requested that you report in Land Cypher Code by telephone daily at 8.00 p.m. to Mount Wise :-
(a) Which Groups are at sea and their approximate location.
