Immediately following the action of Congress authorizing the President to call into service the army and navy of the United States, the North Atlantic squadron, under command of Captain Sampson, was mobilized at Key West. It consisted of the following vessels: Battleships Iowa and Indiana, armored cruiser New York, the monitors Puritan, Terror and Amphitrite, the gunboats Nashville, Castine, Machias, Wilmington and Helena, the cruisers Detroit, Cincinnati and Marblehead, and the torpedo-boats Cushing, Ericsson, Dupont, Foote, Winslow, Porter and Mayflower. These comprised a hard fighting aggregation under a cool and daring fighter. The two first-class battleships were not equaled in fighting power by anything in the Spanish navy, and the New York was one of the best fighting ships of her kind in the world. Commodore Winfield Scott Schley and the fighters of his flying squadron were gathered at Hampton Roads, impatient for orders from Washington to face the foe. Far away in Pacific waters Commodore Dewey was cabled the command to hold himself in readiness to proceed to Manila, and the good ship Oregon, under command of Captain Clarke, was steaming her way around Cape Horn to join the fleet in Cuban waters. In the army equal activity was shown. THE CAMP AT CHICKAMAUGA. Chickamauga Park, near Chattanooga, Tenn., was the point of concentration for the regular troops which were gathered for the war with Spain. It was the initial camp where the mobilization took place, and from which soldiers and supplies were dispatched to seacoast towns within easy striking distance of Cuba. When orders went out from army headquarters at Washington for the movement of the regulars to Chickamauga a thrill of soldierly pride swelled the breast of every man who wore Uncle Sam's blue uniform, and there was a hasty dash for the new camp. There is nothing an army man, officer or private, dislikes so much as inactivity. Fighting, especially against a foreign foe, suits him better than dawdling away his time in idleness, and word to "get to the front" is always welcome.
