How the Royal Navy temporarily searched the wrong way for Bismarck

British commanders had to choose among a return to Germany, a breakout into the Atlantic, or a run toward France while aircraft and escorts were constrained by fuel and equipment failures. Bismarck's long radio transmissions offered valuable bearings, but assumptions about which ships still possessed working direction-finding gear produced a bad plot aboard King George V. Communications security became a liability when higher command did not know the actual location or equipment state of dispersed ships. Rodney's independent position and course, combined with later Admiralty fixes, helped preserve the chance of interception despite confused higher direction.
