The Dardanelles plan without advance warning

How different might the Dardanelles campaign be if the local command's original plan received approval?

If the army and navy arrived together, the operation would be easier and might succeed because the Ottomans would not receive the same warning and time to prepare.

The gap between the naval effort and the later land campaign was a critical operational problem. A coordinated arrival could deny the Ottoman defenders the advance notice that helped them reinforce the objective, improving the chances of forcing the Dardanelles.
