On 27 September 1939, thirty-three men arrived from Argentina in a group called the "Tabaris Highlanders." Gathered from the Anglo-Argentine community, they were supposed to defend the islands from a German attack. Six of these volunteers were rejected on medical and other grounds and returned to Buenos Aires almost immediately. The "commanding officer," a Major Morrough, was one of those rejected. The remainder were enrolled in the Falkland Islands Defence Force, with Ronald Campbell made sergeant as commander and Thomas Dawson Sanderson made corporal. Many were rugby players, including Sanderson, who was president of a rugby club.
