I'm playing Russia versus all other nations on Medium AI. I instigated a quarrel with Turkey and have successfully invaded Bessarabia, Moldovia and Wallachia. Turkey hardly intervened until I reached Bulgaria and gave battle twice.
The first time was straightforward, the Russians had about a 3 to 2 superiority and won the battle of Varna comfortably.
A second Turkish Corps came up and joined the remnants of the first. I was able to concentrate 5 Corps plus Cavalry against them and had a very sizeable advantage. I lost! See screenshot.
What happened? Why did the Russian army break?
