good Mehicans lost? On Santa Anna's side possibly with thousands wounded.
There were indeed Mexicans inside the Alamo fighting in behalf of the Republic. They were referred to as Texians in those days.
From Lt. Col. Travis at the Alamo 1836
“To the People of Texas & All Americans in the World:
Fellow citizens & compatriots—I am besieged, by a thousand or more of the Mexicans under Santa Anna—I have sustained a continual Bombardment & cannonade for 24 hours & have not lost a man. The enemy has demanded a surrender at discretion, otherwise, the garrison are to be put to the sword, if the fort is taken—I have answered the demand with a cannon shot, & our flag still waves proudly from the walls. I shall never surrender or retreat.
Then, I call on you in the name of Liberty, of patriotism & everything dear to the American character, to come to our aid, with all dispatch—The enemy is receiving reinforcements daily & will no doubt increase to three or four thousand in four or five days. If this call is neglected, I am determined to sustain myself as long as possible & die like a soldier who never forgets what is due to his own honor & that of his country—Victory or Death.
William Barret Travis
Lt. Col. comdt
P.S. The Lord is on our side—When the enemy appeared in sight we had not three bushels of corn—We have since found in deserted houses 80 or 90 bushels & got into the walls 20 or 30 head of Beeves
