'Sandmann' was a German and Croat operation against the partisan forces of Josip Broz Tito in the puppet state of Croatia in Axis-occupied Yugoslavia (29 October/3 November 1942).

The objective of the undertaking was the destruction of partisan groups (probably elements of the 5^th 'Krajiski' Brigade), which had escaped from 'Kozara', in the area round Bosanski Novi and Dvor in western Bosnia.

The German contribution comprised elements of the 721^st Grenadierregiment and 714^th Pionierkompanie of Generalleutnant Friedrich Stahl’s 714^th Division, and the Croat contribution two companies of the 4^th Ustase Battalion, elements of the 8^th Artillery Group, and one mountain battery of Pukovnik Arnold Redelstein’s 2^nd Mountain Brigade.

Only the operations order for this operation survived the war, and there is therefore the possibility that the operation may have been cancelled.
