"On paper the Char B1 bis was the most powerful tank in the world in 1940. It was armed with a 75mm howitzer in the hull, intended for infantry support, and a 47mm anti-tank gun in the one man turret.
Although heavily armoured it was slow and had limited range – a consequence of its long development, which had begun in 1926.
This tank was one of many captured by the Germans after the Fall of France. It was issued to Tank Battalion 213, stationed in the Channel Islands. It never saw combat and was taken by the British in 1945 when Jersey was liberated."
