Before this dispatch reached Lecompton the Governor had departed with three hundred United States mounted troops and a battery of light artillery, and arrived in Lawrence early in the morning, where he found matters precisely as described. Skillfully stationing his troops outside the town, in commanding positions, to prevent a collision between the invading forces from Missouri and the citizens, he entered Lawrence alone, and there he beheld a sight which would have aroused the manhood of the most stolid mortal. About three hundred persons Were found in arms, determined to sell their lives at the dearest price to their ruffian enemies. Among these were many women, and children of both sexes, armed with guns and otherwise accoutered for battle. They had been goaded to this by the courage of despair. Gov. Geary addressed the armed citizens of Lawrence, and when he assured them of his and the law's protection they offered to deposit their arms at his feet and return to their respective habitations. He bade them go to their homes in confidence, and to carry their arms with them, as the constitution guarantees that right, but to use them only in the last resort to protect their lives and property and the chastity of their females. Early in the morning of the 15th, having left the troops to protect the town, the Governor proceeded alone to the camp of the invading forces, then within three miles and drawn up in line of battle. Before reaching Franklin, he met the advance guard, and upon inquiring who they were and what were their objects, received for answer that they were the Territorial Militia, and called into service by the Governor of Kansas, and that they were marching to wipe out Lawrence and every Abolitionist in the country. Mr. Geary informed them that he was now Governor of Kansas, and Commander-in-chief of the Territorial Militia, and ordered the officer in command to countermarch his troops back to the main line, and conduct him to the center, which order, after some hesitation, was reluctantly obeyed. The red face of the rising sun was just peering over the top of Blue Mound, as the Governor, with his strange escort of three hundred mounted men, with red shirts and odd-shaped hats, descended upon the Wakarusa plain, where in battle array were ranged at least three thousand armed and desperate men. They were not dressed in the usual habiliments of soldiers, but in every imaginable costume that could be obtained in the western region. Most of them were mounted, and manifested an unmistakable disposition to be at their bloody work. In the back-ground stood at least three hundred army tents and as many wagons, while here and there a cannon was planted ready to aid in the anticipated destruction. Among the banners floated black flags, to indicate the design that neither age, sex nor condition would be spared in the slaughter that was to ensue.
