As the facts thus far given show plainly, the slave-trade had intimate relations with the pirates who operated under the Spanish-American flags, and later with those fitted out from Cuba; for the Panda cleared out from Havana for a cargo of slaves. But she carried no trade goods; her clearance for the African coast was merely a cover for the real purpose in view. Still, she might have brought a cargo of slaves to Cuba but for the interference of a British war-ship. But the American slave-trade lasted for thirty years after the captain of the Panda was hanged, and such acts of piracy as his had long been out of fashion in American waters.
By the act of Congress dated March 2, 1807 (it passed the House by a vote of sixty-three to forty-nine), the importations of slaves into the United States after January 1, 1808, was forbidden. The penalties provided included forfeiture of the vessel, and fines, together with imprisonment, for those involved.
As this legislation had been provided for in the Constitution of the nation, the trade in slaves was naturally brisk in the years immediately preceding prohibition. Thus, from January 1, 1804, to December 31, 1807, 202 ships imported 39,075 slaves into the port of Charleston, South Carolina. Of these ships, 61 were registered at Charleston (though generally owned elsewhere), 59 were owned in Rhode Island, from 1 to 4 in each of several other American ports, and 70 in England. While the prospect of prohibition increased the importations at this time beyond the normal, it is evident that a strong demand for slaves existed among slave-owners. The demand was particularly strong in the Mississippi Valley, where the profits on cotton were enormous. This demand naturally raised the price as soon as lawful importations came to an end. At the same time the existence of the American prohibitory law (England prohibited the trade at about the same time, too) depressed the price on the coast of Africa. Thus a premium was placed on smuggling, and 202 ships were afloat that had been engaged in the trade to one port alone.
All this is to say that while the law drove many ships out of the trade, it added much to the profits of those that remained in it.
Because the trade was continued, an effort was made to strengthen the law in 1818 by increasing the emoluments of informers. Then, by the Act of March 3, 1819, Congress authorized the President to use the naval ships to intercept slavers, and finally by the Act of May 15, 1820, all Americans engaging in the trade were declared pirates, who should be hanged on conviction.
One would be glad to believe that these laws were enacted because the American people had become sufficiently enlightened to appreciate the effects of the trade upon the human race, and especially upon the white people connected with it, but it is impossible to do so. The laws were enacted because of a passing wave of sentiment that had its origin in the work of the pirates herein described. In a dim way people saw that a connection existed between some of the pirates and the slave-trade. The slave-trade was held responsible (properly, too) for some of the horrors of the piracies, and while Congress was legislating against the pirates, it was easy to get acts against the trade passed. Moreover, the desire of the slave-owners to rid their States of free negroes was just then giving strength to the movement for sending those negroes to Africa—Liberia. In short, the prohibitory laws were the result of a sort of hysteria rather than of any real enlightenment of the American people. In truth, we are not so enlightened even now as to appreciate our whole duty toward the inferior race—properly a race of children—we brought from Africa.
As said, prohibiting the trade did but increase the profits of those who disregarded the law, but a more memorable result of prohibition was the effect upon the unfortunate victims of the trade—the increase in the horrors of the middle passage. A brief description of the ships used in the trade will help one to understand how the slaves were affected.
The American slave-ships were usually small vessels, say 100 feet or so long, and 10 or 12 deep. On the way to the coast what was called the slave-deck was laid. By means of beams, stanchions, and rough planks a temporary deck was built 3 feet below the regular deck. The naked slaves were placed upon this deck. In the days of the lawful trade they were compelled to lie down on their backs, shoulder to shoulder, with heads outboard in a row all around the slave-deck. Then other rows of the kind were made on the deck inside of the first row until the deck was entirely covered. When the law prohibited the trade, the slavers increased the number carried to the utmost capacity of their vessels, in order to increase the profits and cover the risks. To do this they compelled the negroes to lie down on their sides breast to back,—"spoon fashion,"—or else they were made to sit in rows, breast to back, from the wall of the ship to the centre. When sitting thus, the only air-space between the two decks was that over the rows of shoulders and between the rows of heads. When lying down, the air-space was greater, but whenever the vessel heeled to the wind, those on the lee side had to lie with their feet higher than their heads, and when the vessel rolled to the waves all of them sawed to and fro over the cracks between the unplaned deck boards. Moreover, the slaves were kept fastened to the deck—they were not allowed to leave their cramped berths for any purpose save only at fixed hours, when they were fed and, in small gangs, were taken to the upper deck for a short airing. In storms the washing of the waves across the deck compelled the crew to put on the hatches and keep them on sometimes for days at a stretch.
Meantime the allowance of water was a pint a day. In short, the slave-ship was a horrible floating cesspool. How the inhuman drivers added to the sufferings of the wretched slaves by the use of the whip, and other means of torture, may be suggested by one story.
When the slaver Brillante, Captain Homans, with 600 slaves in her hold, was overhauled by British cruisers during a calm, and Homans saw that the boats of the cruisers would soon come to the vessel, he got the anchor in position as if for anchoring the vessel. Then the iron cable was stretched along the rail outside of all and held in place by slender cords. To this chain all the slaves were carefully secured by means of ropes and chains. Then, just before the cruisers' boats came into view (it was at night), the anchor was cast loose and the 600 slaves were dragged down to the bottom of the sea.
