Final answer:
Readers considered the military position of William Travis and his followers at the Alamo to be desperate due to being heavily outnumbered and the high casualties they suffered.
Step-by-step explanation:
The readers of the letter considered the military position of William Travis and his followers at the Alamo to be desperate because they were hopelessly outnumbered.
In February 1836, Santa Anna and his army of four thousand besieged San Antonio where the Alamo was located. The defenders, led by Travis, fought fiercely for ten days but were eventually overwhelmed.
The mission was taken and most of the defenders were killed. This overwhelming force and the high casualties on the Texan side contributed to the perception of the situation being desperate.
