Flinging themselves into the saddle, the boys rode rapidly after Lieutenant Grant and were at Colonel Bright's quarters by the time the bugle had called to boots and saddle. In another minute, at the head of a squadron of cavalry, they dashed over the road they had come to know so well.
What happened during the next twenty minutes is history.
Guided by the boys, the reinforcements arrived opportunely to stop the advance of a large body of Mexicans who would have destroyed the water works and have left the inhabitants and the American troops entirely without water.
A few minutes later two batteries with rapid-fire guns put in an appearance, and in less time than it takes to tell it, the Mexicans turned and fled.
It was not General Funston's mission in Vera Cruz to overrun any more Mexican territory, so the Mexicans were allowed to retreat without pursuit; but the lines were strengthened so that from that time on there was never any danger from Huerta's forces, although there were numerous alarms and plenty of scout duty.
During the few minutes of fighting, the boys were in the midst of it and all came through it without a scratch. But it was exciting work and when it was over they were publicly thanked by Colonel Bright for their good work.
"Well," laughed Billie as the three rode slowly back to their home, "that's glory enough for one day. I don't care to be a soldier."
"Nor I!" agreed Donald. "I prefer a quiet life on the ranch."
"Which we are in a fair way to see in a few weeks," commented Adrian. "I have no doubt that General Funston will do as he agreed and find us passage."
"I for one shall be glad to return to the States," said Donald.
