MerryPrankster said:Had the Brits kept going instead of hanging back when they did, the Ottoman troops would have fled the area. Instead, they had the opportunity to bring in reinforcements.
Now, the Brits breaking out of Thrace could prove tricky. However, a large Allied force, so close to Constantinople, would keep the Ottomans quite busy and it would definitely keep the Straits open.
Strange assumption: historically, Ottoman troops have always performed quite well when they had to defend the homeland. In 1914, the army was already reformed, and they had confidence in their generals.
The expeditionary Force did not have even good maps of the peninsula.
What are you anticipating? the EF forcing the narrowest part of the peninsula and taking Constantinople (not to mention Adrianople, and the rest of Trakia??
Gallipoli was an expensive and wasteful exercise, which was undertaken for political rather than military reasons. Even assuming that the EF might have kept their beachhead on the Gallipoli peninsula, it would not have reopened the Dardanelles: the forts on the 2 narrows were always in Turkish hands, and their guns were interdicting any navigation.
Frankly (and on the assumption that a new front against the Ottomans was really necessary) I'd have tried a landing near Smyrna: at least the Entente troops would have had some space to maneuvre, and Smyrna was an important port as well as the second largest city for Turkey.
