recover them for identification and burial. Picked up the following bodies: identified each as best possible and then weighted them down for sea burial: (1) BARKSDALE, Leon T. 863 46 28 (service number).
"Leon and I were both home on military leaves on two different occasions. By the grace of God just before Thomas' last engagement in the early summer of 1945, I took Leon into the Tiemeier Jewelry Store and surprised our mother who was employed there", said his brother.
