For a moment the men were aghast. It might mean the approach of a new and stronger enemy. Then a great cheer rose from every throat. They saw the Stars and Stripes bravely fluttering in the breeze, and knew what it meant. It was the Cruiser Brooklyn entering the harbor.

The cruiser fired her saluting guns.

Boom! Boom!

But the cheers from her men drowned the noise of the guns.

The blue jackets were wild with delight when they saw the American flag at the masthead of the Spanish cruiser.

At this moment a diversion occurred.

Overlooking the harbor was a fort. Now its guns began to fire at the two ships, the cruiser and the gun-boat. Previously they had refrained, because they were afraid they might do as much damage to friend as foe.

Short-handed as he was, it was a difficult matter for Captain Long to handle his guns. But there was no necessity for his doing so. The Brooklyn took the work in hand instantly.

Boom!

The first shot struck the fort. It was old. Its weapons were antique, and it had no chance whatever against the great guns of the American cruiser. Shot after shot struck it, crumbling the masonry to powder.
