Klingenberg’s Knight’s Cross recommendation reads as follows…
“On the 12.04.1941 SS-Hauptsturmführer Klingenberg had the mission of capturing the Danube bridge north of Belgrade in a coup-de-main with his small forward detachment of the Kradschützen-Bataillon.
At 08:00 on this day Hauptsturmführer Klingenberg reached Pancevo, but found that the bridge over the Tamis river had been blown. He crossed over with fishing boats while taking along a few solo motorcycles. Riding on these he and his small troop reached the great Danube bridge north of Belgrade at 11:30. The bridge had already been blown at 06:00. By 15:30 SS-Hauptsturmführer Klingenberg had made a motorboat operational, and crossed over the Danube on this boat with 10 men, 2 MGs and 5 machine-pistols. Along the way the boat ran aground on a sandbank and it was made afloat again following laborious effort. Then the engine stopped, and the boat almost crashed against a bridge buttress. After the motor was restarted Hauptsturmführer Klingenberg reached the southern end of the great bridge at around 16:30.
He created a small bridgehead and sent the boat back to pick up additional troops. Then he personally began marching on foot into the inner part of Belgrade with 10 men. Oncoming Serbian soldiers were persuaded to lay down their weapons with friendly shots.
Riding on several military vehicles which had been taken from Serbian soldiers, Hauptsturmführer Klingenberg proceeded to the war ministry. As the ministry was destroyed and empty, security was established around it. Hauptsturmführer Klingenberg then sent out a Serbian soldier as a messenger in order to find and immediately summon the mayor of Belgrade for the surrender of the city.
In the meantime Hauptsturmführer Klingenberg and a few of his men went to the German embassy. There they met the German military attaché, Oberst Toussaint, and raised the German flag. He brought over the security detail that was by the embassy and awaited the mayor.
He appeared at the German embassy and formally surrendered the city of Belgrade at 18:45, being under the impression that stronger German units had occupied the city.
In order to simulate stronger forces, Hauptsturmführer Klingenberg and his by now reinforced troop drove through the city in vehicles and opened fire on all Serbian soldiers encountered. In addition to numerous smaller detachments that immediately laid down their arms and surrendered, he also went up against stronger formations. An engineer column along with other units were persuaded into laying down their weapons by friendly fire. About 1000 prisoners were taken.
Hauptsturmführer Klingenberg then occupied and secured the German embassy until the arrival of other German units, which reached Belgrade during the night.
Thus Hauptsturmführer Klingenberg completed his mission of capturing the bridge and with it a southern bridgehead, a task that he carried out while responding flexibly to changing circumstances. Furthermore he made the independent decision to force the surrender of Belgrade, and was ultimately able to bring about this intention with only weak forces and while under difficult circumstances.”
