The Mexican investment was not yet complete.
Yet no such thought ever entered Ned's head.

His best friends, Will Allen, the Panther and Obed White, were out there somewhere, if they were still alive, but his heart was now here in the Alamo with the Texans.
He listened intently, but he heard no sound of any Mexican advance.

It occurred to him that a formidable attack might be made here, particularly under the cover of darkness.

A dashing leader like the younger Urrea might attempt a surprise.
He dropped back inside and went to one of the sentinels who was standing on an abutment with his head just showing above the wall.

He was a young man, not more than two or three years older than Ned, and he was glad to have company.
"Have you heard or seen anything ?" asked Ned.
"No," replied the sentinel, "but I've been looking for 'em down this way." They waited a little longer and then Ned was quite sure that he saw a dim form in the darkness.
