It's May 5, 1945, in ITER Castle, a small hilltop fortress in Austria.

His weapon drawn, German army major Yosef Gungel hurries down a dim stone staircase hot on the heels

of an American officer. Seems like this have been common in recent months as Allied forces

fight their way to the heart of Nazi Germany. But today is different. Today, Major Gengel and the

American Lieutenant Jack Lee are on the same side.

They're both part of a small group defending the castle and its prisoners from an attack by more than 100 diehard Nazis.

The staircase leads to the castle's courtyard.

Gongle crouches and follows Lieutenant Lee to the parapet wall as enemy rounds ricochet off the cobblestones behind them.

He's had little time since the battle began to reflect on the strangeness of this situation,

but the spectacle in front of him now brings it home.

Farther along the wall, an elderly French politician roars insults in his native tongue as he gleefully sprays bullets at the enemy outside the

castle. The old man was a prisoner here just a few days ago, but now he's ignored orders to

stay inside where it's safer and is defending the fortress as if it were his real home.

A nearby door swings open and three American GIs edge along the wall toward Lieutenant Lee.

As the Americans make plans in hurried English, Gangle takes a moment to check his weapon.

He's running low on ammo. They all must be by now.

So unless something changes soon, you're going to lose this battle.

When he looks up, he sees the French politician is on the move,

heading toward the castle's gatehouse.

For Gangle, half a lifetime soldiering takes over,

and in an instant, he calculates the angles and comes to a conclusion,

the Frenchman is exposed.
