It all began in 1862 during the Civil War, when Union Army Captain
  Robert  Ellicombe was with his men near Harrison's Landing in Virginia. The
  Confederate Army was on the other side of the narrow strip of land.
  During the night, Captain Ellicombe heard the moan of a soldier who lay
  mortally wounded on the field. Not knowing if it was a Union or Confederate
  soldier, the captain decided to risk his life and bring the stricken man back for

  following morning, heartbroken, the father asked permission of his
  superiors to give his son a full military burial despite his enemy status.

  musical notes he had found on a piece of paper in the pocket of his dead son's

  This wish was granted. This music was the haunting melody we now know as

  "Taps" that is used at all military funerals.
