Despite Halder's hopes, LSSAH was held in reserve attached to XIV Panzer Corps as part of "Generalfeldmarschall" Ewald von Kleist's 1st Panzer Group during the opening stages of the attack. Through July it was attached to III Panzer Corps before finishing August as part of XLVIII Panzer Corps. During this time, the LSSAH was involved in the Battle of Uman and the subsequent capture of Kiev. According to a postwar report by Waffen-SS journalist Erich Kern, the division murdered 4,000 Soviet prisoners in reprisal on 18 August, after finding the mutilated bodies of six dead divisional members who had been executed at Nowo Danzig, north of Kherson. These allegations have been researched using local units' war diaries; no mention of executed German soldiers during those dates has been found. For want of reliable evidence, not even accusations by the Soviet authorities, the allegations remained unproven.
