That was when one enemy was used against a greater enemy. The UK was also aligned with Russia in WW1 and the Napoleonic Wars. To understand any of this one has to recognize that British national security has rested on preventing any single continental power from dominating the continent and thus posing an invasion threat across the Channel. Even in WW2 Britain joined the US on D-Day. This prevented the Soviet Union from marching all the way to France, Holland, etc.
