During the Second World War he was a highly valued staff officer. Gause was initially sent to Africa with a large staff by Oberkommando des Heeres (OKH), the German Army High Command, to act as a liaison officer with the Italian High Command, Comando Supremo. Gause had specific instructions not to place himself under the command of Erwin Rommel, but did so when Rommel told him categorically that the command of all troops in Africa were vested in him.
