Cadet Robert Brett, 1917

Robert Benney Brett was a cadet in training at the Royal Naval College of Canada when he was injured by the Halifax Explosion.

This photograph shows the bandages covering Brett's head wounds, inflicted by flying metal and glass. Brett had commenced training at the naval college in 1915 and, along with his classmates, was waiting to take his final exam when the Mont Blanc exploded. Brett recovered and was one of three Canadian cadets subsequently posted as midshipmen to the British battleship HMS Canada for further training.
