The clash outside Izmit brought serious consequences. The British forces opened fire on the nationalists and bombed them from the air. This bombing forced a retreat but there was a panic in Constantinople. The British commander—General George Milne—asked for reinforcements. This led to a study to determine what would be required to defeat the Turkish nationalists. The report—signed by Field Marshal Ferdinand Foch—concluded that 27 divisions would be sufficient, but the British army did not have 27 divisions to spare. Also, a deployment of this size could have disastrous political consequences back home. World War I had just ended, and the British public would not support another lengthy and costly expedition.
