The Allies thought that defeating the Ottoman Empire would be an extremely simple matter but it was, in fact, not simple (this will be a reoccurring theme for the allies). As they try to take Constantinople, the surf will turn red with the amount of blood spilled from the landing parties. Luckily, they're about to get a boost from the internal strife of the Ottoman Empire. So long as the British promise to help establish an Arab kingdom. A promise they definitely intend to keep. Right???
