Her bulwarks were ten feet thick; her tops were musket-proof.

She had twenty guns of largest size, besides many other pieces of artillery of lesser calibre, the lower tier of which was almost at the water's level.

She was to carry one thousand men, and she was so supported on corks and barrels as to be sure to float under any circumstances.

Thus she was a great swimming fortress which could not be sunk, and was impervious to shot.

Unluckily, however, in spite of her four masts and three helms, she would neither sail nor steer, and she proved but a great, unmanageable and very ridiculous tub, fully justifying all the sarcasms that had been launched upon her during the period of her construction, which had been almost as long as the siege itself.
The Spaniards called her the Bugaboo--a monster to scare children withal.
The patriots christened her the Elephant, the Antwerp Folly, the Lost Penny, with many similar appellations.
