Why did Sam Houston order the retreat of Fannin's men and the retreat of the troops of the Alamo? A he wanted to run for the Mexicans
B so they could March to the US
C more men could build more bridges
D the troops needed more training so that they were prepared

D.

As the ashes of the Alamo continued to smolder, Sam Houston feared another disaster could befall his Texas Army. Mexican forces under General Antonio Lopez de Santa Anna continued to sweep across Texas toward Fort Defiance, the presidio in Goliad that had been seized by the rebels in October 1835 at the onset of the war for independence. Houston ordered Colonel James W. Fannin to evacuate his 400-man force from Goliad and retreat to Victoria, a town 30 miles to the east behind the natural defense of the Guadalupe River. “The immediate advance of the enemy may be confidently expected,” Houston warned Fannin. “Prompt movements are therefore highly important.”

It’s D because he didn’t want his troops to die because, they weren’t trained enough
