Dick was overjoyed. He had formed a strong liking for Major Hertford and he was quite sure that Warner and Sergeant Whitley would be with him. Once more they would be reunited, reunited for battle. He could not doubt that they would go to speedy action as the little town at the junction of the mighty rivers resounded with preparation.

When Colonel Winchester and the boy had saluted and retired from General Grant's tent they saw the smoke pouring from the funnels of numerous steamers in the Mississippi, and they saw thousands of troops encamped in tents along the shores of both the Ohio and Mississippi. Heavy cannon were drawn up on the wharves, and ammunition and supplies were being transferred from hundreds of wagons to the steamers. It was evident to any one that this expedition, whatever it might be, was to proceed by water. It was a land of mighty rivers, close together, and a steamer might go anywhere.

As Dick and Colonel Winchester, on whose staff he would now be, were watching this active scene, a small steamer, coming down the Ohio, drew in to a wharf, and a number of soldiers in faded blue disembarked. The boy uttered a shout of joy.

“What is it, Dick?” asked Colonel Winchester.

“Why, sir, there's my former commander, Colonel Newcomb, and just behind him is my comrade, Lieutenant George Warner of Vermont, and not far away is Sergeant Whitley, late of the regular army, one of the best soldiers in the world. Can I greet them, colonel?”

“Of course.”

Dick rushed forward and saluted Colonel Newcomb, who grasped him warmly by the hand.

“So you got safely through, my lad,” he said. “Major Hertford, who came down the Kentucky with his detachment and joined us at Carrollton at the mouth of that river, told us of your mission. The major is bringing up the rear of our column, but here are other friends of yours.”

Dick the next moment was wringing the hand of the Vermont boy and was receiving an equally powerful grip in return.

“I believed that we would meet you here,” said Warner, “I calculated that with your courage, skill and knowledge of the country the chances were at least eighty per cent in favor of your getting through to Buell. And if you did get through to Buell I knew that at least ninety per cent of the circumstances would represent your desire and effort to come here. That was a net percentage of seventy-two in favor of meeting you here in Cairo, and the seventy-two per cent has prevailed, as it usually does.”
