I would. It was put into the context of the Alamo... period.
Yes, he won the battle but lost the war. Muis bien!
In the context of the Alamo itself, his forced march through a blizzard to get there cost him eight times the men he defeated, and the battle itself cost at least that many again, if not twice that number.
That is not a decisive victory. I would call it winning a particular battle at an unbelievable horrendous cost that if persisted in and replicated would ultimately lose the war.
Yes, he won...but not decisively so. If anything, the Texans and their allies proved to him how costly his victories would be and in that way won their won decisve triumph in losing that battle.
