Operation Bullseye was the code-name of the first Special Operations Executive (SOE) mission to Yugoslavia since its occupation by the Axis forces. It was led by Capt D.T. Bill Hudson with the objective to discover what was happening in Yugoslavia and co-ordinate all forces of resistance there. The mission also included three Royal Yugoslav Army (RYA) officers from Montenegro: Maj Mirko Lalatović, Maj Zaharije Ostojić and Sgt Veljko Dragićević the wireless transmitter (W/T) operator.[1] The group boarded the submarine HMS Triumph in Malta and reached Petrovac on the Montenegrin coast on 20th Sep 1941.[2][3][4]
