Naval intelligence without a quick Enigma break

What if Bletchley Park had taken longer to break German naval codes?

Operations would be less precisely understood, but traffic analysis would still reveal useful patterns in German naval communications.

Decrypting messages differs from analysing the volume, origin, and pattern of radio traffic. German command systems could reveal their activity simply through the amount of communication they generated, particularly when senior staffs tried to micromanage operations. Without a rapid codebreak, British assessments would be slower and less exact, but not blind. Intelligence could therefore still support routing and interception without revealing the exact content of an enemy message.
