Let’s see.
flush with victory, Santa Anna’s army was no longer in a “combat mode” They were celebrating. Wine women and song. Hell Santa Anna his self was with a woman who became known as “The Yellow Rose of Texas”. VERY INTERESTING STORY THERE.
And you cannot replicate the victory?
Look at the manpower reserves of Mexico, and ask yourself why they would ever bother to sign peace with TX?
TX can raise an army of maybe 30k. Mexico at the time could raise a million, if pressed. Most Mexican commanders raise close to 100k to fight Texas because they want to overrun the state and win.
I’ve won before, but that requires a different strategy from San Jacinto. It means putting every man you can stuff into Cavalry and leading a direct assault on Mexico city by pounding through the Gulf coast, and then scaling the heights.
It can be done, but I’ve never won by fighting on TX soil with all the TX troops defending in San Jacinto. You just get overwhelmed and chipped away by Santa Anna.
