TULSA - In April, 1945, US troops driving on Munich got an order the commander didn't really understand.
Lt. Col. Felix Sparks was told to divert to a camp called "Dachau," seize it, contain it, and not let anyone in or out.
This week, the 45th Infantry Museum, based in Oklahoma City, released a powerful short film which tells the story of his decision to split his forces, and personally lead some of them to the camp.
Battle-hardened veterans who were on a first-name basis with violent death openly wept and cursed at what they found when they arrived.
On April 29th of 2015, some of those men returned to Dachau for the 70th anniversary of its liberation.
It's the story of why American troops fight and die, often far from our shores, for ideas and ideals that may not be universal, but have proven victorious time and again.
