Not sure what Bletchley's role would have been because Bismarck was sighted by a Catalina and shadowed by a further one until the Sheffield could take up a surface shadowing position.

A British Catalina aircraft of No. 209 Squadron, piloted by US Navy observer Ensign Leonard B. Smith, USNR (US Naval Reserve), spotted Bismarck at a range of about eight miles. While Ensign Smith flew the aircraft and evaded accurate German antiaircraft fire, his British copilot radioed a report of the enemy warship's location.

Upon acknowledging the contact report, cruiser Sheffield was detached from Force H and ordered to find and shadow the enemy. Later that day, naval observer Lieutenant James E. Johnson in a British Catalina from No. 240 Squadron, relieved Smith's plane and maintained contact with the German battleship until Sheffield took up a shadowing position.
