Only half the regiment was to go, and no horses could be taken, except a few belonging to officers. The capacity of the transports was limited, and though troops were packed into them like sardines into a can, there was only room for 15,000 men, together with a few horses, a pack-train of mules, four light batteries, and two of siege-guns. So, thousands of soldiers, heartbroken by disappointment, and very many things important to the success of a campaign, were to be left behind. Two dismounted squadrons of the Rough Riders were chosen to accompany the expedition, which, with the exception of themselves and two regiments of volunteer infantry, was composed of regulars; and, to the great joy of Ridge and his immediate friends, their troop was among those thus selected. But their joy was dimmed by being dismounted, and Ridge almost wept when obliged to part with his beloved mare. However, as Rollo philosophically remarked, "Everything goes in time of war, or rather most everything does, and what can't go must be left behind." So five hundred of the horseless riders were piled into a train of empty coal-cars, each man carrying on his person in blanket roll and haversack whatever baggage he was allowed to take, and they were rattled noisily away to Port Tampa, where, after much vexatious delay, they finally boarded the transport _Yucatan_, and felt that they were fairly off for Cuba. But not yet. Again came a rumor of strange war-ships hovering off the coast, and with it a frightened but imperative order from Washington to wait. So they waited in the broiling heat, crowded almost to suffocation in narrow spaces--men delicately reared and used to every luxury, men who had never before breathed any but the pure air of mountain or boundless plain--and their only growl was at the delay that kept them from going to where conditions would be even worse. They ate their coarse food whenever and wherever they could get it, drank tepid water from tin cups that were equally available for soup or coffee, and laughed at their discomforts. "But why don't they let us go?" was the constant cry heard on all sides at all hours. During this most tedious of all their waitings, only one thing of real interest happened. They had heard of the daring exploit of Naval Lieutenant Richmond Pearson Hobson, who, on the night of June 3d, had sunk the big coal-steamer _Merrimac_ in the narrowest part of Santiago Harbor, in the hope of thus preventing the escape of Admiral Cervera's bottled fleet, and they had exulted over this latest example of dauntless American heroism, but none of the details had yet reached them.
