On May 28th, 1949, a party of Scouts, aged between 11 and 15 years, visiting Sully Island were cut off by the rising tide from a causeway which led to the mainland. Most of the boys got safely across, but two of them were forced off the causeway by the strong tide. The leader of the party returned to help the elder boy but in the struggle he too became exhausted. Margaret Vaughan (aged 14 years) saw from the beach the difficulties they were in. She undressed and swam towards them over a distance of some 30 yards in cold, rough water and against strong currents due to the rising tide. On reaching them she towed the boy to the shore while he supported himself by grasping the straps of her costume and his leader's coat. At about ten feet from the shore a life belt was thrown in which the boy was placed by the other two and the three reached the shore safely. Margaret Vaughan's action probably saved the life of the Scout leader as well as that of the elder boy.
