I believe that the Allied Forces gamble at Gallipoli, to attack Constantinople and force Turkey to back out of the war failed miserably, due to such an ill thought out plan, terrible planning skills and bad organization.
's original idea, was simply to send in the Navy, without the support of the army as well, this actual plan began in February, two months before the army got involved as well. Lord Fisher did not want to send in his best ships, because he thought they would be needed against Germans in the Baltic. He was worried that the ships might be damaged or sunk by Turkish guns, which, three ships actually were.
, with the army now involved, the plan was that the Allied Troops, would have landed on the Gallipoli Peninsula, they would have then taken control of the Turkish forts stationed in the Dardanelles, and cross overland into Constantinople.
Meanwhile, as they crossed overland, the Navy could then sail through the Dardanelles, and attack constantinople from the sea. If the plan had succeeded, it could have forced Turkey out of the war, leaving Germany weaker, and then some neighboring countries, Greece and Bulgaria, might have joined the was on the side of the Allied Nations. Allied Forces would then have been to strong, and would have forced Austria out of the war, leaving Germany completely on it's own in the war. This bold plan could have won the war for the Allied Forces, yet it failed miserably. This was due to many things.
mission to land at Gallipoli, was a complete disaster, bad organization meant the mission itself lost many lives, The British believed Constantinople could be taken in three weeks, instead, it lasted ten months in all, and the Allied Forces failed in their objective.
