The "Ostsack" (east sack) of the Krivasoo bridgehead, defended by the Soviet 6th and the 117th Rifle Corps, were confused by the Strachwitz Battle Group's diversionary attack on 6 April. The attack deceived the Soviet forces into thinking that the German attack intended to cut them out from the west flank. The actual assault came directly at the 59th Army and started with a heavy bombardment. The positions of the 59th Army were attacked by dive bombers and the forest there was set afire. At the same time, the 61st Infantry Division and the Strachwitz tank squadron pierced deep into the 59th Army's defences, splitting the two rifle corps apart and forcing them to retreat to their fortifications. Marshal of the Soviet Union Leonid Govorov was outraged by the news, sending in the freshly re-deployed 8th Army. Their attempt to cut off the Tiger I tanks was repelled by Lieutenant Günther Famula, who received a posthumous Knight's Cross for these actions, keeping their supply lines open. On 7 April, Govorov ordered his troops to switch on to the defensive. The 59th Army, having lost another 5,700 troops from all causes, was withdrawn from the bridgehead. For these successes Strachwitz received the Knight's Cross with Oak Leaves, Swords, and Diamonds on 15 April 1944. News of the award had reached his headquarters on the early morning of 15 April via teleprinter message. The official presentation was made a few weeks later by Hitler.
