George Trenchard

George Trenchard was a human who was in charge of a prison guarding the Master during the latter part of his imprisonment by UNIT. Shortly after the Master was imprisoned at Trenchard's facility the Master persuaded him, (either through hypnotism or coercion) that "enemy agents" were working against him and the country. These "enemy agents" were also responsible for recent ships being sunk in the area. George Trenchard died following the Master revealing his contact with the Sea Devils and a subsequent Sea Devil attack, he was killed after he shot a Sea Devil. (DW: The Sea Devils)
