The recalls cause confusion throughout the entire Ottoman Army. Liman von Sanders was central to its functioning and was responsible for the defense of the straits.
Indeed, and he wasn't much help. Turkish officers had anticipated the true landing positions while Sanders was expecting the Entente to land elsewhere. He also kept troops in reserve rather than defending the beaches, meaning that some of the Allied landings could have been to heavier casualities.
He was also unavailable for a time during the actual landings (because he was waiting for a landing elsewhere), if the recall of Germans had happened then some Turkish commander would have been put in charge and maybe having a commander actually paying attention to what was happening would mean a better Ottoman performance in the initial landings as well.
