and united into the (EFO) for duty on Lake Ladoga. The battlegroups acted independently but maintained close operational ties with Naval Detachment K. They were made up of twenty-three
Siebel ferries (seven heavy-artillery-type ferries mounting two to four 88 mm guns each; six light-artillery-type ferries mounting smaller-caliber
flak guns; six transport, six repair, one hospital and one HQ ferries), as well as nine infantry boats (, a.k.a. ), each capable of carrying 40 fully equipped soldiers. Four of these boats were outfitted as minesweepers; three were kept as transports; one was rigged as a hospital boat and one as a HQ boat. In addition, another heavy
assault boat () also acted as a HQ boat.
The Siebel ferries were originated by aircraft designer Friedrich ('Fritz') Siebel and intended for use in Germany's planned 1940 invasion of England,

. They consisted of two heavy army bridging
pontoons braced together with iron cross-beams and covered by a sturdy wooden deck. The ferries initially had a pair of
Ford truck engines in each aft pontoon end, connected to standard water screws. Further power came from three surplus aircraft engines mounted on an elevated scaffolding spanning the rear deck. The aircraft engines, however, were later dispensed with as they consumed considerable fuel and required excessive maintenance.

In all, Fritz Siebel had a total of 30 vessels with 2,400 personnel under his command.
Operations
The EFO suffered losses during a raid to destroy Soviet radio station, lighthouse and coastal artillery emplacement on the strategically important
Sukho Island (; ) from the southern coast of Ladoga, at the main supply route to Leningrad.
The idea of the operation was presented to the Germans by the Finnish
Paavo Talvela.
The German-run operation, codenamed
Operation ''Brasil'' (), began on the evening of October 21, 1942; by the morning of October 22, 1942, Axis forces had reached Sukho Island and launched an attack. Though the radio station and the lighthouse were damaged and the

and armored boats, all the way back to its base along the northern shore of Lake Ladoga. When approaching Sukho Island, one light ferry (''SF 12'') run aground and several other ferries went to assist it. However one of the light ferries (''SF 22'') was hit by Soviet coastal artillery fire and one heavy (''SF 13'') and one light ferry (''SF 26'') that had gone to assist the grounded ferry ''SF 12'' also became grounded despite the efforts to get them loose. Ultimately, all three had to be abandoned. During the return voyage one heavy ferry (''SF 21'') had to be abandoned when it started to take in water so badly that they would not have made it back to the base. An infantry boat (''I 6'') towed by the ferry was also lost. Losses suffered by the EFO during the raid were heavy. The heavy artillery ferries ''SF 13'' (grounded) and ''SF 21'' (damaged, later scuttled), the light artillery ferries ''SF 12'' (grounded) and ''SF 26'' (grounded) and the infantry boat ''I 6''—casualties for the naval and landing forces were 18 men dead, 57 wounded (one of them fatally), and 4 missing.
One of the lost light ferries and the infantry boat ''I 6'' were captured by Soviet forces.
Analysis
The operations of the international flotilla were a failure. The Siebel ferries of EFO had good armament but they were far too slow and had too short a range for effective operations. They were almost "sitting ducks" to the Soviet patrol boats, gunboats and bombers. As their personnel came from the , with no sea-going experience, operations in the often harsh weather conditions were extremely difficult.
