Crockett and six others were holed up in the long barracks savagely fighting for every second of life when the soldiers who had been advancing on them pulled back. A Mexican General called out to them, 'Do you hear that? The fighting is over. You are all that remain. Surrender and I swear that you will be treated with Honor as true fighting men."
After a few seconds of listening for fighting nearby, Crockett called out his surrender. They were led from the mission and taken to Santa Anna's command tent by the General and his men. When they walked in Santa Anna was going over a map. After a second, the brutal dictator lifted his eyes to look at the prisoners and said, "I told you no prisoners, kill them immediately." Crockett pulled a knife from his belt and lunged at Santa Anna but 6 bayonets found his chest.
I believe that this was from a memoir of the Mexican General who he had surrendered to. To me, this death is no less heroic or honorable than if he had died in the courtyard.
