What possible object could the Spanish war-vessels have in this, was a question asked by every one, as soon as the intelligence became known.

The balloon which rose from the "Numancia" had a car attached, but there was clearly no one in it. Therefore the balloons were not to be used for purposes of observation.

The people in New York saw the balloons as they successively rose from the four vessels, and wonderingly watched their progress.

They saw the first of them gently sail toward the city until about over the Roman Catholic Cathedral on Fifth Avenue. Then a dark object seemed to fall from the car, the lightened balloon shot upward, the object struck the roof of the cathedral there was a fearful explosion, a trembling of the earth as if an angry volcano were beneath, and the crash of falling buildings followed.

Through the great clouds of dust and smoke it could be seen that not only was the cathedral shattered, but that the walls of every building adjacent to the square on which it stood were down.

_The Spaniards were dropping nitro-glycerine bombs into the city from the balloons_. They knew how long it would take the breeze to waft the air-ships over the built-up portion, and it was an easy matter to adjust clock-work in the car to cause the dropping of the torpedo at about the proper time.

Accuracy was not needed. A sh.e.l.l, filled with fifty or a hundred pounds of dynamite or nitro-glycerine, would be sure to do terrible damage anywhere within a radius of three miles around Madison Square.

A second balloon dropped its charge into the receiving reservoir in Central Park, luckily doing no damage, but throwing up a tremendous jet of water. The third and fourth balloons let fall their dejectiles, the one among the tenements near Tompkins Square destroying an entire block of houses simultaneously; the other on High Bridge, completely shattering that structure, and so breaking the aqueduct through which the city obtains its water supply.

The Spanish admiral now ceased firing voluntarily and sent a message by flag-of-truce announcing his intention to continue the throwing of balloon torpedoes into the city until it capitulated, and, in order to avoid further destruction of property, he renewed the proposal already made.

General Grant, on receiving this message--for the citizens had literally forced him to take active command of the troops--simply remarked:

"Let him fire away!"

But the Safety Committee vehemently protested; and finally, after much discussion, induced Grant to send back word that the terms were accepted.

The situation was, in truth, one of sadness--of bitter humiliation. The Empire City had fallen, and lay at the mercy of a foreign foe. The immense ransom demanded must be raised and paid, or the work of destruction would be resumed until the defenders of the bay removed their torpedoes from the Narrows and permitted the Spanish forces to enter and occupy the metropolis.

VI.

THE FLAG WITH THE LONE STAR.

As it was manifestly impossible to obtain fifty millions of dollars in specie and foreign notes within New York--for all the money in the vaults of the banks and the treasury had long since been sent to other cities--the general government a.s.sumed payment of the amount demanded by the Spaniards, which, however, it was decided not to make until just before the expiration of the last of the five days of grace.

As will now be seen, this was a fortunate decision. The unremitting bombardment which had been maintained by the four vessels off the Long Island sh.o.r.e had so greatly reduced their supply of ammunition that it became necessary to send for more: and for this purpose the "Vittoria"

was dispatched to meet a transport which had been ordered to sail from Cuba at about this time.

On the evening of the third day the weather a.s.sumed a threatening appearance, and the "El Cid" left her position near Fort Hamilton for a more secure anchorage near Sandy Hook. The other ships stood out to sea.

It stormed heavily during that night, and before evening on the morrow one of the strongest gales ever known in this vicinity had set in.

The situation in which the Spanish flag-ship now found herself was critical. She had put down her two bower anchors, but they were clearly insufficient to hold her. To veer out cable was dangerous, for it was not known how near the ship was to sunken torpedoes; to allow her to drag was to run the double chance of striking a torpedo or going ash.o.r.e.

During the night she parted both cables, and the morning found her firmly imbedded in the beach off the Hook. Of the other vessels, the "Numancia" only was in sight.

The signal men, however, could see black smoke on the horizon; and this they anxiously watched, expecting momentarily to make out the "Arapiles"

and "Zaragoza." Shortly after daybreak, a thick fog settled down, completely cutting off the seaward view.

In the signal station were General Grant and several members of the Safety Commission. The ransom money was in readiness, and the intention was to pay it over during the morning.

At about eight o'clock, heavy firing was heard from the sea.

It was too far distant to be accounted for by a supposed renewal of the bombardment by the Spanish ships, even under the a.s.sumption that they had thus broken the truce.

The watchers at the signal station looked at each other in astonishment, and eagerly waited for the fog to lift.

An hour later, the mist began to clear away. The sight that met the eyes of the spectators was one never to be forgotten.

The "Numancia" was evidently ash.o.r.e on the East bank. Her fore and mainmasts were gone, and clouds of dark smoke were lazily ascending from her forecastle. Suddenly, the whole ship seemed to burst into a sheet of flame, there was a deep explosion, the air was filled with flying fragments, and a blackened hull was all that was left of the proud man-of-war.

The "Arapiles," about two miles further out to sea, was making a gallant defense against three strange vessels. Two, lying at short range on her quarters, were pouring in a fearful fire; the third, which had evidently been engaged with the "Numancia," was rapidly bearing down upon her, apparently intending to ram.

Who could the strangers be?

The flags which floated from their mast-heads bore a strong resemblance to our own, yet they were not the stars and stripes; for the stripes were replaced by but two broad bands of red and white, and in the blue field there was but a single star.

"Chili, by Jove!" e.j.a.c.u.l.a.t.ed some one in the signal station.

He was right.

The new-comers were the "Huascar," the "Almirante Cochrane" and the "Blanco Encelada," the three armored vessels of the South American Republic.

It was the "Huascar" which was now bearing down upon the "Arapiles."

Suddenly, the Chilian monitor was seen to slacken her speed and change her course.

She no longer meant to ram; the necessity had ceased. At the same time, the other Chilian vessels ceased firing.

The Spanish ensign on the "Arapiles" had been lowered. In a few minutes after it rose again, but this time surmounted by the Chilian flag.

Then the four vessels stood in toward the Hook.

The watchers on the signal station now waited in breathless suspense.

The "Arapiles," with a prize crew from the other vessels to work her guns, was to be made to attack her former consort, the stranded "El Cid;" and that vessel, aware of her danger, was now firing rapidly at her approaching enemies.

It was not reserved, however, for the Chilians to complete their victory by the capture of the great ironclad.

The giant was to be killed by a pigmy scarce larger than one of his own huge weapons. A smaller steam-launch slowly crept out from the Staten Island sh.o.r.e. But two men could be seen on board of her--one in the bow, the other at the helm.

"They don't see us yet, Ned," said the man in the bow.

"No; they have all they can do to take care of the other fellows. Look out! Are you hurt?"

A sh.e.l.l from the Chilians just then came over the Hook, and, bursting under the water near the launch, deluged the boat with spray.

"Not a bit," said the other.
