Winnable? How? The army that was to defend Thrace was just a bunch of illeterate trouble makers, without any motivation. Officers who were to lead this crowd were instead struggling with one another, and the higher-ups in the administration. And the administration? They were totally blind to pre-war political situation and the military pact shaping up against them.
That would be a rare miracle if the Ottomans had any success. But, as I say, it is rare!
I am with you on your statement though, Balkan War is the beginning of the END. And I go further to say it is the final nail in the coffin, and not the WW1.
So many military experts agreed it would be winnable if the Ottomans played a defensive role rather than a offense.
Goltz Pasha actually devised a defensive plan but Nazim Pasha threw it in the bin believing the Ottomans can go on the offensive by fighting them one by one.
Plan was to lock the Balkan countries into a state of attrition where they would accumlate high casualties and lose materiel the costs would be too much for them. I dont think the Ottomans could have avoided high casualties either.
Our biggest problem was not just officers fighting among themselves but the navy was in a inadequate. Greeks took the islands even blocked troops and supplies from being crossed into Balkans.
Land war could have been won perhaps if it was locked into a state of attrition.
At the end we lost huge chunks of Europe for good and signalled the end.
Losing to countries which we ruled for centuries was pretty embarassing.
