The steam tonnage of the British Empire—mostly engaged in the oversea carrying trade—had increased from 204,654 tons in 1851 to 417,717 tons in 1856, whereas the steam tonnage of the United States engaged in the oversea carrying trade had increased from 62,390 tons in 1851 to 115,045 tons in 1855, but had decreased to 89,715 tons in 1856. It should be noted that while a large proportion of the steam tonnage of Great Britain consisted of iron vessels, many of them being screw steamers, the steam vessels of the United States were very nearly, if not all, still constructed of wood and propelled by side-wheels.
The first symptoms of the decadence of the American merchant marine were the falling-off in the sales of American tonnage to foreign countries—the reduction being from 65,000 tons in 1855 to 42,000 tons in 1856, declining to 26,000 tons in 1858 and to 17,000 tons in 1860, a falling-off of 75% in five years—then in the total tonnage of vessels built in the United States, which fell from 583,450 tons in 1855 to 469,393 tons in 1856, and to 378,804 tons in 1857.
These facts refute the historic falsehood that the Alabama and her consorts were the first and immediate cause of decadence in the American merchant marine. As a matter of fact, neither the depression preceding the Civil War, nor the depredations of Confederate privateers, nor the Civil War itself, have had any material bearing upon the decline of American shipping during the last fifty years. The gigantic task of driving the American flag from the ocean has been accomplished
