Tony:My father, Edward J. Doyle, was also attached to the 5th Engr. Battallion, 5th Mar.Div., Iwo Jima.As a kid, I found a copy of the Marine Corps. Hymn and sung it to him on the Marine Corps. Birthday one year. I don't know what made me do that except that I knew he was proud of having served.He got a kick out of it.
