As far as the ongoing war between the Aztec and Tlaxcaltec, there were 3 major Aztec offensives(i don't think calling the large Aztec march on them a flower war fit the definition)on Tlaxcaltec territory. All of them with heavy casualties but the last one breaking through Tlaxcaltec forces leaving their city exposed. However, the fighting was so heavy the Aztecs turned back. Cholula, nominally allied with the Tlaxcaltec, located smack in the middle of the fighting, decided to flip to the Aztec side afterward. Tlaxcaltec people pre Cortez were fending off the Aztec but they were definitely under heavy pressure and probably felt betrayed by Cholula changing sides and also what happens to be Cortezs first major massacre. Coincidence, yea, you do the math.
