'Heiderose' was a German operation against the partisan forces of Marshal Josip Broz Tito in the Sekovica area of German-occupied Yugoslavia (17/25 July 1944).

Even as the 'Fliegenfänger' undertaking was in progress, General Maximilian de Angelis’s 2^nd Panzerarmee attempted to check a large partisan force moving out of Bosnia into the western part of Serbia. On 17 July 1944, units of SS-Brigadeführer und Generalmajor der Waffen-SS Desiderius Hampel’s 13^th SS Gebirgsdivision 'Handschar' (kroatische Nr 1) and SS-Brigadeführer und Generalmajor der Waffen-SS Karl Reichsritter von Oberkamp’s 7^th SS Gebirgsdivision 'Prinz Eugen' began their effort to destroy the communist stronghold to the north-west of Sekovici.

By all accounts 'Heiderose' was a major success: the Germans claimed to have killed 947 partisans, and captured large quantities of matériel including one anti tank-gun, two mortars, 22 machine guns, more than 800 rifles, and nearly 500,000 rounds of small arms ammunition.
