What went wrong at Gallipoli?

On the 9th of January 1916, the last remaining Allied troops on the Gallipoli peninsula were evacuated. Despite catastrophic predictions, the withdrawal went off without a hitch and the entire force escaped with only a few casualties. It was the only bright spark in a campaign marked by failure. After naval attempts to force the Dardanelles straight failed, the amphibious landings had fared even worse. Fierce Ottoman opposition stopped the Allies in their tracks and trench warfare quickly took hold. There were heavy casualties on both sides, not only from the fighting but from the terrible conditions. After a succession of failed attacks, the decision was finally made to withdraw. In this episode of IWM Stories, Alan Wakefield explores what went wrong at Gallipoli and why the evacuations were the only success.
