Gyles Mackrell DFC GM (9 October 1888 – 20 February 1959) was a British tea planter known for organising a rescue of refugees retreating from the advancing Japanese across the Burma-India border during World War II.
Mackrell was a shikari in Shillong, Assam with his own elephant transport business and also acted as an agent for the tea agents Octavius Steel & Co. On 4 June 1942, some refugees managed to cross the Dapha River, which had been swollen by monsoon rains, by forming a human chain and told Mackrell about the great difficulty others were experiencing trying to cross the Chaukan Pass at the Burma-India border. When the monsoon winds and river calmed he decided to use his elephants to help. "These elephants are quite capable of such a daunting task," he said and by September had rescued about 200 people, mainly British and Indian soldiers, feeding and caring for them until help arrived, despite falling severely ill with fever himself for some time.
For his services, Mackrell was awarded the George Medal (GM) in January 1943.
