Eastern Europe
From Tardis Wiki, the free Doctor Who reference
In the history in which the Ironsides were never discovered by the Eleventh Doctor, the Germans turned their forces against the Soviet Union after being defeated in the Battle of Britain by the Ironsides. However, they were forced to retreat to Germany after the Ironsides paved the way for Allied forces to liberate France, allowing the Russians to spread across Eastern Europe at the other end of the Allied pincer movement.
