There was a great shout in the Mexican lines, but the round shot spent itself against the massive stone walls of the mission.
"They'll have to send out a stronger call than that," said Davy Crockett contemptuously, "before this 'coon comes down." Travis went along the walls, saw that the Texans were sheltering themselves, and waited.

There was another heavy report and a second round shot struck harmlessly upon the stone.

Then the full bombardment began.

A half dozen batteries rained shot and shell upon the Alamo.

The roar was continuous like the steady roll of thunder, and it beat upon the drums of Ned's ears until he thought he would become deaf.
He was crouched behind the stone parapet, but he looked up often enough to see what was going on.
