Have any better source than wikipedia ? One day truce ? Shishman attacked with goal to defeat Serbia. Not to have any kind of truce ! That makes no sense ! And you think someone will tolerate ~15 000 armed men in their lands ?!!!!!!!! What would Byzantines say about that "one day truce" ? Leaving them to deal with Serbia alone and to be devastated ? Byzantines had no army capable of invading. That would also mean establishing strong defensive and offensive positions in SERBIAN LANDS( Velbazhd and it's surroundings were in Serbian hands at that time)! And I don't know for what reason you copied it here ? In this battle Bulgarian army was crushed by Serbian heavy cav and knights led by Dushan. Reason why Bulgaria did not lost more land is because of a little bit stupid, but a very pious man who wanted to stop killings and to be friend not enemy ! Bulgarian nobles offered union with Serbia, but he refused !!! Reason why Dushan did not invade Bulgaria was because his wife was Bulgarian PRINCESS and that means Bulgaria was ally (some sources claim something as semi-vassal because on Bulgarian throne were relatives of Dushan) to Serbia ! So your "theory" of "backstabbing" is silly. Bulgaria still had army. Defeated Romans. IF they were stronger why they did not crush Serbia in "fair" fight.

To short it. Point of this disscusion is who had better heavy cav. Bulgaria lost medieval fights with Serbia and it's imperial dreams died. But even best thing that will prove I am right is Ottoman invasion. There is no mention of Turks being afraid of Bulgarian cav. I could not find a single Bulgarian victory against Ottomans in 14th and very early 15th century(don't counting some minor successes of Rebels) even when Turks were weaker than before invading Serbia. While Turks were butchered by Serbian men-at-arms and knights/nobles in about 6 battles !!! So people bring your frustrations and complexes to a halt because no one ever proved and won't that Bulgaria had stronger heavy cav in mid 14th - 15th century !
Bobi_TWR: Speaking about backstabbing, Bulgarians are very well known for that and a lot more ! I see that insulting is pretty much only argument you have.
