“There they come,” announced a man sitting his horse at Ernest’s left. “If we don’t lick ’em Peggy McCormick will. She lives yonder on the bay and owns a square league of this prairie. They’re treading down her grass.”

It was two o’clock. The Mexican army were in sight at last, advancing from the left, along the marsh of the bay. Their colors flew, bayonets and scabbards occasionally glistened, the officers’ trappings sparkled. Infantry and cavalry they were—yes, and artillery, for there was a cannon drawn by mules.

On they marched, steadily—and their drums were heard beating in cadence. They made a compact mass, as if they did not intend to stop but to proceed right ahead to the ferry crossing.

Ernest’s heart thumped rapidly. No orders issued from the general, who was composedly standing with Colonel Hockley and Colonel Rusk and others of his staff, between the Twin Sisters battery and the Colonel Burleson regiment, and watching the Mexican advance.

“By cracky, they’ll have to fight or swim—or do both!” exclaimed Jim. “What are we here for, anyway, do they think?”

At this moment a bugle call shrilled gaily from the Mexican ranks. Out galloped the artillery mules, dragging the one cannon to the furthest of the timber islands, opposite the Millard infantry. It was a challenge! From the trees puffed a cloud of smoke, and accompanying the heavy report, in among the live-oak branches along the bayou rattled a storm of grape-shot.

But the Twin Sisters were answering. How Colonel Neill and his artillerymen hustled!

“Lie down, men! Lie down!” shouted the regular and riflemen officers. The cavalry, well back in the shelter of the festooned live-oaks, were safe. General Houston still stood erect. The Twin Sisters and the Mexican piece were booming back and forth.

Again sounded the bugle, and again. The Mexican infantry deployed a long line, and ran forward through the grass, firing—halting, firing, loading and running again, making for Colonel Burleson’s regiment. The Twin Sisters were turned on them—the regiment began to fire, “Crack! Crackity crack! Crack-crack-crack!”—and the Mexican soldiers scurried back.
