From BBC News
"In early May 1945, American and German soldiers fought together against the Nazi SS to free prominent French prisoners of war. It is believed to be the only battle in the war in which Americans and Germans fought as allies.
Hans Fuchs remembers how Itter Castle was converted into a prison by the Nazis in 1943.
"We saw everything from our school window," he said, "a double barbed-wire fence… and floodlights so that the whole night was lit up like day."
Schloss Itter, which dates back to the Middle Ages, was a sub-unit of the Dachau concentration camp.
It was used for VIP prisoners, prominent politicians and military figures that the Nazis wanted to use as bargaining chips.
They included two former prime ministers of France, Edouard Daladier and Paul Reynaud, as well as the elder sister of Gen Charles de Gaulle, Marie-Agnes Cailliau.
In May 1945, the last days of the war in Europe, the German guards at Schloss Itter fled. But the French prisoners were trapped, as the woods around the castle were full of roaming units of the Waffen SS and Gestapo secret police.
The French sent out two prisoners on bicycles to find help.
Stephen Harding, author of the book The Last Battle, says one of them managed to contact a

US Capt Jack Lee teamed up with Gangl's men to take on the SS
A highly decorated Wehrmacht officer, Gangl had become opposed to the Nazis and was collaborating with the Austrian resistance.
"Gangl realised he could not protect them [the prisoners], he only had about 20 soldiers who were loyal to him," Mr Harding said.
Taking a big white flag, Gangl met up with the closest American unit, the 23rd Tank Battalion of the US 12th Armoured Division, led by Capt Jack Lee.
Lee offered to lead a rescue mission to the castle.
SS attack
A small group of Americans, accompanied by Gangl and some of his men, made their way to Itter, parking their Sherman tank close to the castle entrance.
At dawn on 5 May, they were attacked by the Waffen SS, who blew up the US tank, but were unable to storm the castle.
"There was only one casualty," says Mr Harding. "Josef Gangl was killed by a sniper."
Hans Fuchs, who was 14, watched the battle from his family's farm. "There was machine gun fire for hours," he said. "We saw clouds of dust and smoke."
That evening, once the fighting stopped, he went down towards the castle.
"The tank was still burning," he said. "I saw how around 100 SS men were taken prisoner… They had to give up everything and were taken away on lorries."

What a fascinating story of having austrians Americans fighting against the SS in the last days of the war to protect this Castle. Almost something out of the movie Kelly's Heroes

Hmmm. Interesting. The posting below, from BBC, reads as follows: "In early May 1945, American and German soldiers fought together against the Nazi SS to free prominent French prisoners of war. It is believed to be the only battle in the war in which Americans and Germans fought as allies."
So from what I read, it WASN'T "US and NAZI" soldiers that were allied. It was US and Wehrmacht soldiers fighting AGAINST the NAZI SS troops. The SS were hard core NAZIs. The Wehrmacht was Germany's regular army and the SS "policed" them in many occasions to "keep them in line". It was like the Communist Party in Russia. Only 3% of the population belonged to the Communist Party, but they ran the country by controlling its governmental institutions. in germany, the numbers might have been a little higher, but not all that much. The highest I've seen is 10%, but that doesn't mean that's accurate. Many joined the party for economic reasons but didn't buy in to the propaganda - like Shindler, for example, who actually protected and saved many Jews.
