N.1

201 In view of continued attacks on Atlantic routes by enemy submarines the following principles are to be adhered to in routing East going convoys.

A. Routes are to be varied as much as possible within the 

  areas forbidden to West going traffic as laid down in 

  paragraph 24 of Approach Routes.2

B.   The meridian on which the routes of convoys turn to

  the northward is to be constantly varied with due

  observance of the actual ice situation.

C.  The routes across the Atlantic from the turning point

  to the initial Rendesvous are not necessarily to adhere

  to the great circle, but should be varied as much as

  possible.

  Possibility of using BELLEISLE STRAITS from H.S.

  Convoys3 is also to be considered and reported on. The

  main principle to be borne in mind is that routes should

  be varied. 1926.

[Anti-Submarine Division]/Force Commander U.S.N. [VAdm. William S. Sims]/French Liaison Officer.” And below that are the initials “NKY,” which was presumably the transcriber. Along the top of the page is a printed number giving ordering information concerning the pad on which the telegram was typed.
