What could the fleet have done at Constantinople?

If the fleet reached Constantinople, would it have enough troops to take the city and deal with local resistance?

The plan relied on sailors, marines and naval guns. Its hoped-for coercive effect is judged plausible, but whether the Ottoman authorities would panic remains uncertain.

The plan relied on sailors, marines and battleship guns once the fleet reached Constantinople. Its political effect depended partly on the hope that the Ottoman authorities would panic, an outcome explicitly left uncertain. The counterfactual judgment is that a fleet which survived the passage would probably have forced a decision even without a substantial landing force. The threat of shelling the capital supplies the proposed pressure, while the ability to occupy the city remains a separate problem raised by the question.
