'Florett' was a German and Croat operation by Generalleutnant Hans Mickl’s 392^nd Division (kroatische) against the 13^th 'Primorsko-goranska' Assault Division of Marshal Josip Broz Tito’s partisan forces in the Mrkopalj region which it held since the capitulation of Italy in September 1943 (30 June/1 July 1944).

The 3/846^th Grenadierregiment was moved from Otočac to the area to the south-east of Josipdol to free the 33^rd Ustase Battalion for the operation, which began on 30 June with the attackers divided into three groups, in the form of the 2/847^th Grenadierregiment and parts of the Kampfgruppe 'Rijeka' advancing toward Lokve-Delnice, the 392^nd Aufklärungsabteilung and 2/846^th Grenadierregiment advancing from Dreznica using narrow mountain roads toward Mrkopalj, and the 33^rd Ustase Battalion with two pieces of artillery of the 1/392^nd Artillerierregiment and one company of the 3/846^th Grenadierregiment advancing toward Vrbovsko.

By the evening of the first day the second group had covered 26 miles (42 km) of difficult mountain road to reach Mrkopalj and surprise the partisan town command, forcing it to flee. The other groups encountered only light resistance from the 1^st and 2^nd Detachments as most of 13^th Division was committed to an attack on Bosiljevo together with the 15^th 'Slovenia' Division in order to relieve pressure on Zumberak, where another anti-partisan operation was under way.

After destroying several partisan warehouses and barracks, the German group left Mrkopalj and advanced to the east to aid the garrison in Bosiljevo. The Germans and Croats could not undertake the permanent garrisoning of the area, and after the destruction of partisans' local infrastructure left the Mrkopalj area.
