During the fighting on 29 April, Weber was wounded and evacuated to the make-shift field hospital in the basement of the Reich Chancellery. It was his sixth combat wound of the war.[3] While there he briefed area commander, SS-BrigadeführerWilhelm Mohnke as to the situation along front lines of the government district.[4] He was awarded the Knight's Cross of the Iron Cross by Mohnke on 29 April.[4]
