Investment In the early hours of February 23, residents began fleeing Béxar, fearing the Mexican army's imminent arrival. Although unconvinced by the reports, Travis stationed a soldier in the
San Fernando church bell tower, the highest location in town, to watch for signs of an approaching force. Several hours later, Texian scouts reported seeing Mexican troops outside the town. and
Gregorio Esparza, whose family climbed through the window of the Alamo church after the Mexican army arrived. Other members of the garrison failed to report for duty; most of the men working outside Béxar did not try to sneak past Mexican lines. By late afternoon Béxar was occupied by about 1,500 Mexican soldiers. When the Mexican troops raised a blood-red flag signifying
no quarter, Travis responded with a blast from the Alamo's largest cannon.
Skirmishes The first night of the siege was relatively quiet. Over the next few days, Mexican soldiers established artillery batteries, initially about from the south and east walls of the
Alamo. A third battery was positioned southeast of the fort. Each night the batteries inched closer to the Alamo walls. On February 26 Travis ordered the artillery to conserve powder and shot. Two notable events occurred on Wednesday, February 24. At some point that day, Bowie collapsed from illness, leaving Travis in sole command of the garrison. Several Texians ventured out to burn the huts Six Mexican soldiers were killed and four others were wounded. A
blue norther blew in on February 25, dropping the temperature to . Neither army was prepared for the cold temperatures. Texian attempts to gather firewood were thwarted by Mexican troops. On the evening of February 26 Colonel Juan Bringas engaged several Texians who were burning more huts. According to historian J.R. Edmondson, one Texian was killed. Four days later, Texians shot and killed Private First-Class Secundino Alvarez, a soldier from one of two battalions that Santa Anna had stationed on two sides of the Alamo. By March 1, the number of Mexican casualties was nine dead and four wounded, while the Texian garrison had lost only one man.
Reinforcements Santa Anna posted one company east of the Alamo, on the road to
Gonzales. Almonte and 800
dragoons were stationed along the road to
Goliad. Throughout the siege these towns had received multiple couriers, dispatched by Travis to plead for reinforcements and supplies. The most famous of his missives, written February 24, was addressed
To the People of Texas & All Americans in the World. According to historian Mary Deborah Petite, the letter is "considered by many as one of the masterpieces of American patriotism." Copies of the letter were distributed across Texas, and eventually reprinted throughout the United States and much of Europe. On February 26, after days of indecision, Fannin ordered 320 men, four cannons, and several supply wagons to march towards the Alamo, away. This group traveled less than before turning back. Fannin blamed the retreat on his officers; the officers and enlisted men accused Fannin of aborting the mission. became sole Texian commander at the Alamo on February 24.|alt=Head and shoulders of a clean-shaven man with wavy hair.

Impatient with the delay, on February 27 Travis ordered Samuel G. Bastian to go to Gonzales "to hurry up reinforcements". According to historian Thomas Ricks Lindley, Bastian encountered the Gonzales Ranging Company led by Lieutenant
George C. Kimble and Travis' courier to Gonzales, Albert Martin, who had tired of waiting for Fannin. A Mexican patrol attacked, driving off four of the men including Bastian. In the darkness, the Texians fired on the remaining 32 men, whom they assumed were Mexican soldiers. One man was wounded, and his English curses convinced the occupiers to open the gates. On March 3, the Texians watched from the walls as approximately 1,000 Mexicans marched into Béxar. The Mexican army celebrated loudly throughout the afternoon, both in honor of their reinforcements and at the news that troops under General
José de Urrea had soundly defeated Texian Colonel
Frank W. Johnson at the
Battle of San Patricio on February 27. Most of the Texians in the Alamo believed that Sesma had been leading the Mexican forces during the siege, and they mistakenly attributed the celebration to the arrival of Santa Anna. The reinforcements brought the number of Mexican soldiers in Béxar to almost 3,100. The arrival of the Mexican reinforcements prompted Travis to send three men, including
Davy Crockett, to find Fannin's force, which he still believed to be en route. The scouts discovered a large group of Texians camped from the Alamo. Just before daylight on March 4, part of the Texian force broke through Mexican lines and entered the Alamo. Mexican soldiers drove a second group across the prairie.
Assault preparations Legend holds that at some point on March 5, Travis gathered his men and explained that an attack was imminent, and that they were greatly outnumbered by the Mexican Army. He supposedly drew a
line in the ground and asked those willing to die for the Texian cause to cross and stand alongside him; only one man (
Moses Rose) was said to have declined. Most scholars disregard this tale because there is no primary source evidence to support it (the story only surfaced decades after the battle in a third-hand account). At some point prior to the final assault, Travis reportedly assembled a conference to inform the men of their dire situation, giving them the chance to either escape or stay and die for the cause. Susanna Dickinson recalled Travis announcing that any men who wished to escape should let it be known and step out of ranks. Hardin says: "Reliable Mexican accounts, however, suggest a different story." On March 4 (according to Todish) or March 5 (according to Hardin), Santa Anna proposed an assault on the Alamo. Some senior officers recommended that they wait for two 12-pounder cannons anticipated to arrive around March 7. Mexican Lieutenant Colonel de la Peña wrote that Travis' men had been "urging him to surrender" and "on the 5th he promised them that if no help arrived on that day they would surrender the next day or would try to escape under the cover of darkness." De la Peña's sources were a woman from San Antonio, Travis' slave Ben, and women who had remained inside the Alamo. Mexican General Vicente Filisola also noted that Travis, through a female intermediary, proposed a surrender that would spare their lives, but Santa Anna would only accept unconditional surrender. During the assault, Santa Anna arranged for troops from Béxar to be excused from the front lines so that they would not be forced to fight their own families. The last Texian verified to have left the Alamo was James Allen, a courier who carried personal messages from Travis and several of the other men on March 5. ==Final assault==
