Sir Charles Macpherson Dobell (1869-1954), The Royal Welch Fusileers, served in field command positions in Africa and Palestine during World War One, and he was knighted and promoted to Lieutenant-General following his endeavours as commander of an Anglo-French force tasked with the capture of Cameroon. He was mentioned in dispatches nine times.
