What was the Russian intention to use its mobilized military, if at all, in case the Bulgarians kept pushing?
A land advance to attack Bulgaria through Romania?
Pressure on the Ottomans to invite a Russian landing force to Constantinople to "protect" it.
How would Russia have proceeded if Bulgaria got "lucky" and captured Constantinople before engaging against the Serbs and Greeks in Macedonia?
At the time the 'Slavic' Bulgarians had shifted their alliance/aignment to Austria-Hungary.
Really, so perhaps Austria really would have loved to see Bulgarian success in Thrace. Or, Bulgarian success might have bothered everybody, with the Russians thinking the Bulgarians are pro-Austrian, and the Austrians thinking the Bulgarians are pro-Russian.
A majority of Russia's exports went through the straits. Having them shut for whatever reason would and still be an economic disaster for Russia.
Hmm, perhaps the prospect of two opposing states controlling the straits, one on the European side and another on the Asian side, was more disturbing than both sides of the straits going to a single power. I suppose that fighting close to Constantinople for any period of time would end itself to Bulgaria and Turkey trading artillery volleys across the waterway, and commercial shippers being unwilling to carry on trade in those circumstances? Thoughts?
