PQ-17
PQ-17 was one of the most disastrous naval episodes of WW2 for the allies. Naval intelligence led the British Admiralty to believe that German surface vessels, particularly the Tirpitz, were going to attack the large convoy PQ-17. It fell to First Sea Lord Admiral Dudley Pound to decide what action to take. He ordered the escort vessels to leave the convoy to pursue the supposed German threat, and he ordered the merchant ships to “scatter”. Each tried to make its way individually to Russia, but with no warships to protect them they were exposed to enemy air attack and vulnerable to U-boats. Of the 35 merchant vessels, 24 were sunk, prompting Winston Churchill to name the disaster “one of the most melancholy naval episodes in the whole of the war”.
