It was employed in protecting marine communications in the Adriatic, mostly from partisan naval attacks. On 1 March 1944, the Flotilla was extended and re-designated the 11. Sicherungsdivision.

A remarkable figure was the Canadian captain Thomas G. Fuller, son of the Canadian Chief Dominion Architect Thomas William Fuller, who in 1944 took command of the 61st MGB flotilla. Operating from the island of Vis he supplied the partisans by pirating German supply ships. He managed to sink or capture 13 German supply boats, was involved in 105 fire fights and another 30 operations where there was no gunfire. Characteristically for the Yugoslav operations theatre, Fuller attributed a good part of his success to the blood-curling threats uttered by the Yugoslav partisan who manned the MGB's loud hailer: a 400 ton schooner was captured with its whole cargo and whose crew gave up without a struggle because of the explanation of what would be done to them personally, with knives, if they disobeyed.
