'Ferdinand' (ii) was a German operation against the partisan forces of Josip Broz Tito in the Fruska mountain region of Syrmia in the puppet state of Croatia within occupied Yugoslavia (19/21 September 1943).

The German forces were elements of the 2/1235^th Reserve-Grenadierregiment of Generalleutnant Hans Freiherr von Falkenstein’s 45^th Division, elements of the 86^th Reserve-Pionierbataillon and 46^th Pionierersatzbataillon, elements of the 17^th Panzerjägerkompanie, an Artilleriebatterie of Generalleutnant Heinrich von Behr’s 173^rd Reserve-Division, elements of the 12^th Panzerkompanie zbV, 1, 2 and 3/Polizeiregiment 'Kroatien', 6^th Polizei Panzerkompanie (five tanks and six armoured cars), SS Sonderkommando 'Otto', 64^th Panzerzug, and one railway security battalion.

Supervised by the Befehlshaber der Ordnungspolizei für Kroatien, this was a totally unsuccessful operation which failed even to bring the partisans to battle. The Germans lost one man, and claimed only eight partisans killed.
