During the battle of San Jacinto April 21, 1836 9 Texans died, compared to the 1,360 Mexicans who lost their lives. The fighting quickly went from rifles to hand-to-hand. As the Texans overwhelmed the Mexicans, the Mexicans fled into the swamps and marshes.
In the book The Raven: A Biography of Sam Houston, it is noted some of the Mexicans were screaming “Me no Alamo !” as Texans gave the Mexicans the same quarter that was shown at the Alamo and Goliad.
The battle only lasted about 18 minutes. But the slaughter continued for an hour or so after the main battle ended.
