Britain's foremost military museum has apologized for "accidentally" labelling as terrorists Jewish soldiers who fought the Nazis as part of the British army, the Jewish Chronicle Online reported on Tuesday.

A photograph of the Jewish Brigade from October 1944 on the website of the Imperial War Museum in London was captioned: “Terrorist activities: Men of the First Battalion Jewish Brigade during a march past.”

The Jewish Brigade was formed in 1944 as part of the British Army. It was composed of Jews from pre-state Palestine, and commanded by British-Jewish officers. It primarily fought against the Germans in Italy.

After a complaint from the Simon Weisenthal Center, the image was removed from the website. In a letter to the director general of the museum, Dr. Simon Samuels, the Center’s director for international relations, wrote: "The Jewish Brigade under British command were heroes who combated fascist terrorists in Italy. They were eye-witnesses to the annihilation of their people as they joined the liberators of the camps."

He added: "To call them ‘terrorists’ is the greatest Holocaust revisionism imaginable. This has tarnished your museum and betrays the cause of British integrity."

A spokeswoman for the museum apologized. "This was the historic label we received alongside the photograph, accidentally uploaded in order to give the public access to our comprehensive archives." She said that the photo was removed and that the museum was looking in detail at all other captions.
