High Quality Content by WIKIPEDIA articles! Operation Seagull ("Unternehmen Möwe" or "Seemöwe" in German) was an Abwehr II/Brandenburger Regiment sanctioned mission launched in September 1940. The object of the mission was to infiltrate Britain in preparation for Operation Sealion (Unternehmen Seelöwe in German). Operation Seagull was planned in connection with Abwehr's remit of intelligence gathering for Operation Sealion. Despite being planned and launched, the mission was aborted midway during the sea crossing to Ireland. At the time of Seagull's conception, Abwehr chief Wilhelm Canaris had already issued orders that regional Abwehr stations known as "Ast's" were not to attempt to infiltrate into Britain via Ireland for the foreseeable future, due to the dismal failure of Operation Lobster I ("Unternehmen Hummer" in German) in July 1940. However, Seagull was directed by Army Group Northern France/Belgium via the Brandenburger Regiment attached to Abwehr II anyway.
