"It's come. Boys! Steady now, to the finish!"

"Look here, Sir! I'm going to try for it." Thode caught his host by the arm. "I can slip out before they have the house surrounded and find a horse somewhere. If they down me, one man more or less here won't make any difference, and it's a chance!"

"Look!" Gentleman Geoff waved the young engineer to a narrow window beside the entrance door.

Down the straight level expanse of the Calle Rivera clattered an unending stream of horsemen, their accoutrements jingling a sinister diapason as they poured helter-skelter across the plaza in the waning moonlight. Tatterdemalion as they were, the ragged army were well-organized as Thode saw at a glance; no haphazard, leaderless crew was this, for at their head rode a diminutive, jockey-like figure, his face glistening and ebony in the eerie radiance, his teeth flashing white as he turned in the saddle. The Little Nigger had come!

His company halted in an irregular line against the eastern end of the plaza, flung themselves from their horses and came on in a rushing, yelling horde. A weak scattered volley rattled from the dwellings about the square, but the raiders made unswervingly for what was obviously their main objective, the Blue Chip, where most of the male population, unlimited alcohol and a fabulous ransom in gold were theirs for the taking.

They had reached the center of the Calle, when Gentleman Geoff barked a brief command and a withering blast of shots rang forth from the besieged garrison. The advancing line crumpled, wavered, then at a cat-like yowl from its dusky leader, closed in and came forward with an answering roar.

Kearn Thode sprang from his point of vantage and faced the other man once more with undiminished determination in his eyes.

"I've got to get to the barracks—it means death to us all if I stay here! Isn't there a door on the other side of the house somewhere back of the patio?"

"Yes. It opens on a little alley that leads to the plaza." It was the girl's eager voice which replied.

"And the Carranzistas, the government troops, are ten miles away to the north. I'm going to ride for it, Sir, it's the only chance. I can slip out of that alley and around the edge of the plaza to where their horses are picketed. There'll be interference there, and I may have a running fight for it, but I'll take the odds."
