Holland's battle plan was to have "Hood" and "Prince of Wales" engage "Bismarck" while "Suffolk" and "Norfolk" engaged "Prinz Eugen" (which, Holland assumed, still steamed behind "Bismarck" and not ahead of her). He signalled this to Captain John C. Leach of "Prince of Wales" but did not radio Wake-Walker, who as Commander of the 1st Cruiser Squadron directed "Suffolk" and "Norfolk", for fear of disclosing his location. Instead, he observed radio silence. Holland hoped to meet the enemy at approximately 02:00. Sunset in this latitude was at 01:51 (ship's clocks were four hours ahead of local time). "Bismarck" and "Prinz Eugen" would be silhouetted against the sun's afterglow while "Hood" and "Prince of Wales" could approach rapidly, unseen in the darkness, to a range close enough not to endanger "Hood" with plunging fire from "Bismarck". The Germans would not expect an attack from this quarter, giving the British the advantage of surprise.
