A battle flag that witnessed the D-Day operation from atop the USS Texas will be displayed in a Houston museum for the first time since World War II.

The flag was just put on exhibit Friday at the Houston Museum of Natural Science in honor of the 70th anniversary of the Allied invasion of the Normandy coastline on June 6, 1944.

The flag had been given by the ship's crew to Emil Saul, a navigator aboard the USS Texas who was severely wounded when a German shell hit the vessel while it was part of an operation to capture the port city of Cherbourg.

Saul gave it back to the USS Texas, now a memorial named the Battleship Texas that sits in the Port of Houston.
