Henry Morgenthau was the American ambassador to Turkey in 1915, and probably the most accurate and intelligent foreign observer of Turkish affairs at the time. He said, "The whole Ottoman state, on that eighteenth day of March, when the Allied fleet abandoned the attack, was on the brink of dissolution." He describes a city in panic, with the government planning on fleeing and many elements within the city ready to welcome the Allies. He was always of the opinion that the moment the fleet arrived off Constantinople, the Turks would surrender.
That does make things easier. How about this then?
18th March: The Navy is luckier with the minefields - 4 ships hit mines and ony one is lost. John de Robeck decides to press on.
19th March: 2 more ships are struck by mines, both are lost. Despite this the commanders on the scene decide to contine. The Ottoman forces run out of shells.
19th March: The Ottoman government flees into the Asian side of the Empire. Constantinople erupts into chaos. Law and order break down. Wild rumors sweep the city.
21st March:
Forward elements of the fleet engages the German ship Goeben which had been in harbour at Constantinople, but it escapes into the Black Sea.
A message is sent asking for the surrender of Constantinople. There is no effective civil authority left to respond. Some factions within the city ask the Allies to enter to restore order.
24th March: British and French forces enter the city unopposed. The commanders on the round are still unable to communicate with the Ottoman government.
The Ottoman forces on Gallipoli have also lost contact with their own central command - no orders have been made for their withdrawal, so they dig in.
The Mediterranian Expeditionary Force (MEF) begins to deploy around Constantinople.
27th March: The neck of the Gallipoli peninsula has been closed, albeit by inadequate forces to hold against a determined assault by the Ottoman forces penned there.
The commander of the MEF, sends runners along the peninsular with a message offering a ceasfire whilst surrender terms can be worked out.
29th March: The offers of ceasfire are rejected. Probing attacks are made on the MEF's lines, which are only rebuffed with fire support from the battleships. As one officer said later, more by luck than judgement.
1st April: Substantil reinforcements for the MEF arrive and disembark.
Any one have any issues with that?
What will the British be doing about the Ottoman forces on the other side of the Straits?
What will the Ottoman government be up to, or has it collapsed. Will the Allies have to pick one of the military commanders on Gallipoli to negotiate with as a representative of his government?
