'Blücher' (ii) was a German unrealised plan for a five-division major amphibious assault from Crimea across the Strait of Kerch into the Kuban area of the Caucasus as part of 'Blau III' (July 1942).
The operation was first laid out in the Führerweisung Nr 43 of 11 July 1942, but was in fact finally executed in a much smaller 'Blücher II' form on 2 September 1942.
