"Why, he marched for the Lower Agency yesterday morning with forty-five men, as soon as he heard of the outbreak there. They were ambushed by the Indians at the ferry across the Minnesota and, though they seem to have fought splendidly, all the men were killed except fifteen, who finally got back here. Captain Marsh himself was drowned in trying to swim the river. So, you see, there is a third of our force cut off at one blow. But a messenger was sent after Major Galbraith,--he is the agent, you know, at the Upper Agency,--at the same time that one went for Lieutenant Sheehan. Major Galbraith started yesterday for St. Paul with a company of half-breed recruits for the Union army. They are called the Renville Rangers. They ought to be back here pretty soon and will add fifty more men. Then there are a good many refugees, probably one hundred, who can fight, and we have several cannon, with a regular army sergeant in charge of them. The Indians, you know, are deadly afraid of cannon. So we ought to be able to make a pretty good defence, though I wish there were a stockade." "Did you say that Major Galbraith's company is made up of half-breeds?" inquired Al, remembering with a shudder the evil face of the wretch who had shot his father and whom he himself had killed. "Yes. But most of them are reliable fellows, otherwise they would not be willing to leave their country and go South to fight the rebels." By this time they had reached the headquarters building, and Al saw, standing in front of it, five or six of the Indians who had brought them in. "Who are those Indians, Wallace?" he asked. "They are some of the party who rescued us." Wallace looked closely at the red men, who were standing idle with their ponies, evidently waiting for some one who was inside the building. "Why, those are Sissetons from the Upper Agency," he said. "Probably John Otherday, Solomon Twostars or some of the Renvilles are with them. They have been going around the country all to-day and last night, warning white people and bringing them in and there are other parties of Sissetons and Wahpetons doing the same thing; though it's mighty dangerous business, for the hostiles are almost as bitter against them as against the whites. Very few of the Upper Indians seem to have joined the uprising. They are mostly Christians, you know, and their conduct shows the great work of the missionaries." The boys entered the headquarters building, and though Lieutenant Sheehan was surrounded by many men, all urgently anxious to transact their business with him, Al presently found an opportunity to tell him of Tommy's capture and to ask that men be sent after him. The officer listened intently to the story and when it was finished, laid his hand kindly on Al's shoulder.
