This band, living in forest and swamp, was always ready to strike a blow for the free-state cause. The slavery men were getting the upper hand, and Northern families who had settled in Kansas began to look to John Brown for protection. The "border ruffians" grew worse and worse, attacking small defenseless settlements, burning homes and carrying off cattle. Sometimes it was only the fear of retaliation from Brown's company that kept the raiders from still greater crimes. Occasionally they met; once they fought a battle at Black Jack, and twenty-four of the enemy finally surrendered to nine of Brown's men. One of the leader's sons was badly wounded, and the father had to nurse him in the woods.

Affairs grew worse during the summer. The vilest scum of the slave states poured into Kansas, and the scenes on the border grew more and more disgraceful. There were pitched battles, and at last the governor of the territory, thoroughly scared, surrendered his power into the hands of the slave-holders, and fled for his life. The slave-state men thought that the time had come to strike a blow that should settle the question in Kansas permanently. They prepared to gather an army in Missouri, intending to cross into Kansas, and so terrify settlers from the North that they would make no further resistance. Conditions looked desperate to John Brown, and he left the territory for a short time to see what he could do to get help for his cause.

A large band of emigrants from the North were on the march toward Kansas, and Brown rode to meet them. The emigrants had heard of him, and welcomed him to their midst. He encouraged them and urged them to fight for freedom, and went on his way hoping to rouse more free-state men to enter Kansas.

The East was now thoroughly awake to the lawless situation on the border, and a new governor, Geary by name, was sent out from Washington. Meetings were held in the large cities, and money, arms, and men began to pour into Kansas. Several hundred men from Missouri attacked Osawatomie, which was defended by Abolitionists, and a battle followed. John Brown was there, and when his party won the day he gained the nickname of "Osawatomie Brown," by which he was generally called thereafter.

Fired by this success, the leaders of the free-state army planned to capture Lawrence. The new governor feared that such an act would mean the beginning of a general civil war, and did his best to prevent it. He succeeded in this. The free-state men were divided into two parties, those whose aim was to have Kansas admitted to the Union as a free state, and those who, like John Brown, were bent on abolishing slavery throughout the United States. Governor Geary assured the former men that Kansas would be free soil, and he tried to induce Brown to leave that part of the country for a time in the interest of peace. Brown was willing to do as Governor Geary wished, thinking that Kansas was safe for the present. He wanted to turn his attention to other parts of the country, where he thought he was more needed. In September, 1856, he started east with his sons. He was now a well-known figure, hated by all slave-owners, a hero to Abolitionists, and distrusted by that large number of men whose object was to secure peace at any cost.

There were many people in the North at that time who were helping runaway slaves to escape from their masters, and in certain parts of the country there were stations of what was called the "Underground Railroad." Negroes fleeing from the tyranny of Southern owners were helped along from one station to another, until they were finally safe across the Canadian border. The law of the country said that negro slaves were like any other form of property, and that it was the duty of citizens to return runaways to their masters. There were also scattered through the border states a number of men whose business it was to catch fugitive slaves and take them back south. These men were usually of a brutal type, and the poor refugee who fell into their clutches was made to suffer for his attempt at escape. Story after story of the sufferings of slaves came to John Brown's ears, and he felt that it was his duty to throw himself into the work of the Underground Railroad, and help as many slaves as possible to cross into Canada.

This work was not enough for him, however; he wanted to strike some blow at the slave-owners themselves. The Alleghany Mountain range was one of the main roads for fugitives, for there men could hide in the thick forests of the mountainside, and could make some show of defense when the slave-catchers and bloodhounds came in pursuit. John Brown knew this country well. He traveled through the North, talking with other men who felt as he did, and trying to work out a plan which should force the country to decide this question of negro slavery. At last he decided to make a raid into Southern territory, and free slaves for himself.

In the heart of the Alleghanies, and almost midway between Maine and Florida, is a great natural gateway in the mountains. Here the Potomac and the Shenandoah Rivers meet, and seem to force their way through the natural barrier. This pass is Harper's Ferry, and in 1859 it was the seat of a United States arsenal. To the south was a country filled with slaves, who looked to Harper's Ferry as the highroad to freedom. Not far from the arsenal rose the Blue Ridge Mountains, the heights of which commanded the pass. It was John Brown's plan to lead men from the Maryland side of the Potomac River to attack the arsenal, and when it was captured to carry arms and ammunition across the Shenandoah to Loudoun Heights in the Blue Ridge, and hide there. From here his band could make raids to the south, freeing slaves, and shielding them from their masters, while using the mountains for a shelter.

There were many other men in the United States bent on destroying slavery, but few so impulsive as John Brown. His plan was rash in the extreme, and even its success would have profited only a few slaves. But Brown was a born crusader. The men who followed him were all impulsive, and many of them were already trained in the rude ways of frontier life. They knew what he had done in Kansas, and were ready to fight on his side anywhere else. They had a real reverence for John Brown. The tall man with the long, almost white hair, keen eyes, and flowing beard was no ordinary leader. He had the power to convince men that his cause was just, and to hold them in his service afterward.

In June, 1859, John Brown, with two of his sons, and two friends, started south. He rented a farm about five miles from Harper's Ferry, in a quiet, out-of-the-way place. There were several cabins in the neighborhood, and as his followers gradually joined him, they occupied these shelters. A daughter kept house for him during the summer. The men farmed in the daytime, and planned their conspiracy at night. The leader did everything he could to win the friendship of his neighbors. He had some knowledge of medicine, and attended all who were sick. Frequently he preached in the little Dunker chapel near by. He was always ready to share his food or give the shelter of his roof to any travelers. Slowly he collected guns and ammunition, and late in September sent his daughter north, and arranged to make his attack. At first some of the other men objected to his plans. One or two did not approve of his seizing the government arsenal, and thought they should simply make a raid into Virginia as the slave-state men had formerly carried war into Kansas. Their leader, however, was determined, and nothing could turn him. Already he feared lest some suspicion of his purpose might have spread, and was eager to make his start. He set Sunday night, October 16th, as the time for the raid. That morning he called his men together and read to them from the Bible. In the afternoon he gave them final instructions, and added: "And now, gentlemen, let me impress this one thing upon your minds. You all know how dear life is to you, and how dear life is to your friends. And in remembering that, consider that the lives of others are as dear to them as yours are to you. Do not, therefore, take the life of any one, if you can possibly avoid it; but if it is necessary to take life in order to save your own, then make sure work of it."
