For three days the work went on, the greater portion of the grain accumulating in the loyal farmer's granary preparatory to being carted to camp. But, late in the afternoon of the fourth day, Washington received word that a force of British cavalry had been seen within twenty miles of Valley Forge, and this news, considered in connection with a well-founded rumor that spies were, or had been, within the lines, led him to take prompt measures to secure the large store of grain.

For this duty twenty men of the Wyoming Company were detailed, and Barnabas Otter and Nathan were of the number. So many of the officers were sick or disabled that the command of the little party fell to the lot of Corporal Dubbs. Shortly after supper they formed in the company street and marched quietly through the camp, heading southwest toward Philadelphia. They passed out of the lines between Knox's batteries and Woodford's redoubt, from which point the farmhouse of Jacob Troup was rather more than a mile distant.

It was as bitter and stormy a night as the army at Valley Forge could remember in all that winter. That morning a brief thaw had been succeeded by a cold snap, which formed a hard crust on the snow that thickly covered the ground. Since afternoon fresh snow had been falling, and now the flakes were coming down in a dense, fine mass. Aided by a cutting wind drifts were gathering here and there, and it was impossible to see more than a few yards in any direction. The cold was still intense.

Under these circumstances the thinly-clad and poorly-shod men suffered greatly as they marched on in the teeth of the storm, leading with them four horses that were to haul the grain to camp in the farmer's big sledge. But not a word of complaint was uttered. The thought that the success of their mission meant bread for the army kept their spirits up, and like true heroes they faced the cold and snow. No doubt the brave fellows longed for a fight to heat their blood, but there was little chance that any of the British would be hovering near on such a night as this.

On they went, holding their musket-stocks with numbed fingers. In a black line they straggled through the storm, up hill and down, across patches of timber and low scrub, now knee-deep in fresh snow-drifts, now plodding over the wind-swept crust beneath. At last the leader gave the word to halt. It was in a hollow partly sheltered from the wind, and straight ahead, toward Philadelphia, the snowy landscape merged duskily into the night. To the left a narrow lane led fifty yards to the farm buildings of Jacob Troup. Word of the coming had been sent to him, and a cheery light was flashing in house and barn.

"All's well," declared Corporal Dubbs. "I expected nothing else, for the Britishers ain't the kind of chaps to stir from their warm fires in such weather. But precautions won't go amiss, and I'm going to post half a dozen pickets to watch while the rest of us load the grain."

Accordingly he selected two men, and gave them orders to advance to the left and take their stand on a road that lay some distance to the rear of the farm buildings. "Amos Brown," he said, "you and Tom Relyea march in the opposite direction—off here to the right—and keep on till you come to the road that leads to the Schuylkill beyond Valley Creek."

The corporal now turned to Barnabas Otter, pointing one numbed hand straight ahead to the southwest, in a direction at right angles to those indicated to the other sentries. "Comrade, you know who lives over yonder?" he asked.

"Abner Wilkinson," replied Barnabas. "I've seen the place often. The owner is a rank Tory."

"Ay, he's said to be," admitted the corporal, "and I reckon opinion is right. He certainly looked mighty sour when we stript him of his grain and stock. Well, to proceed, just back of Abner Wilkinson's barn is a broad lane that connects further on with the main highway from Philadelphia. It's bordered by woods, and if the enemy come at all, they'll likely come that way. So you post yourself on that little hill overlooking the road beyond the barn—it's not much over a quarter of a mile from here. Nathan Stanbury will go with you as far as the orchard this side of the house, and that's where I want him to stay. Do you understand?"
