Cause

Fliegerkorps X had not been informed of the naval sortie despite sending signals to Marinegruppe West about Luftwaffe air operations over the North Sea. When Marinegruppe West requested air support on 23 February, the reply confirming destroyers were at sea arrived too late, leaving a Kampfgeschwader 26 bomber crew without warning about friendly vessels in the area.

Event

On 22 February 1940, six Kriegsmarine destroyers sailed into the North Sea as part of Operation Viking. A Kampfgeschwader 26 bomber attacked the formation, striking destroyer Leberecht Maass at around 7:56 p.m. Minutes later, a larger explosion destroyed destroyer Max Schultz, which broke apart and sank. The operation was subsequently called off with only sixty survivors recovered.

Consequence

A formal inquiry exonerated the bomber crew, finding that no recognition flares had been fired from the ships and no warning had been issued. The disaster highlighted severe deficiencies in inter-service communication between the Kriegsmarine and Luftwaffe, and the loss of two destroyers with most of their crews represented a significant early blow to German naval strength.
