of this, the Mayor surrendered to his forces, at which point Klingenberg gathered a number of German flags from the embassy and ran them up various flagpoles in the city. The Yugoslav troops gave up, believing that there had been a general surrender. Shortly, another smaller force of 15 Germans came into the city and started also pretending to be a larger group, by driving captured vehicles repeatedly around the city so as to appear to be greater in number. Sometime later, the actual German Army arrived at the outskirts of the city, expecting to have to fight their way into the city (which had a substantial troop presence), they for a while refused to believe the city had been captured by Klingenberg. Belgrade was then fully occupied by the German Army later the same month and Belgrade became the seat of the puppet Nedić regime, headed by General Milan Nedić. Klingenberg was awarded the Knight's Cross of the Iron Cross for the capture of the city. Battle of Kapyong The battle occurred during the Korean War and the Chinese Spring Offensive of April 1951. The Chinese forces outnumbered the UN battalions by a factor of five to one, or by a factor of greater than ten to one. Two battalions of the 27th British Commonwealth Brigade, each of them consisting of about 700 soldiers, the Australian 3 RAR and the Canadian 2 PPCLI, supported by the artillery of the New Zealand 16th Field Regiment and 15 American Sherman tanks, withstood the assault of the full Chinese 118th Division, numbering about 10,000-20,000 men, in continuous fighting from 23 April to 25 April. The action was of crucial strategic significance as the Kapyong Valley was the traditional invasion route to Seoul, and potentially would enable the encirclement of US forces in Korea. The Australian 3 RAR resisted the Chinese attacks on Hill 504 during 23/24 April until threatened with being surrounded, and then retreated off the battlefield, together with the American tanks. These UN units were no longer engaged in the battle. The Chinese then assaulted the Canadian 2 PPCLI defending Hill 677 in a last stand, who were outnumbered in the combat engagement area by at least ten to one. With his battalion encircled, abandoned by supporting units, and without possibility of resupply of ammunition, Lt. Col. Stone issued the order "No retreat, no surrender", and resisted mass attacks of
