The battle for Castle Itter was fought near the Austrian village of Itter on May 1945, in the last days of the Second World War. US soldiers joined forces with Wehrmacht riflemen, along with Polish and French prisoners and resistance fighters, to defend an Austrian castle against German SS attackers in one of the most unusual battles of the war. This expansion presents the historical characters which participated in the defense (including the M4 Sherman, "Besotten Jenny") and authentic castle locations, along with German hostiles representing the 17th SS Panzergrenadiers laying siege to the castle.
