So much for the labor of these 150,000 men; labor wasted in vain. Let us now look at the cost of life. It is not possible to ascertain the exact loss suffered up to this time, in killed, deceased by ordinary diseases, and in wounded; for some die before they are mustered into the service of the United States, and parts of the army are so far distant from the seat of Government that their recent losses are still unknown. I rely for information on the last report of the Secretary of War, read before the Senate, April 10, 1848, and recently printed. That gives the losses of parts of the army up to December last; other accounts are made up only till October, or till August. Recent losses will of course swell the amount of destruction. According to that report, on the American side there had been killed in battle, or died of wounds received therein, 1,689 persons; there had died of diseases and accidents, 6,173; 3,743 have been wounded in battle, who were not known to be dead at the date of the report. This does not include the deaths in the navy, nor the destruction of men connected with the army in various ways, as furnishing supplies and the like. Considering the sickness and accidents that have happened in the present year, and others which may be expected before the troops reach home, I may set down the total number of deaths on the American side, caused by the war, at 15,000, and the number of wounded men at 4,000. Suppose the army on the average to have consisted of 50,000 men for two years, this gives a mortality of fifteen per cent. each year, which is an enormous loss even for times of war, and one seldom equalled in modern warfare. Now, most of the men who have thus died or been maimed were in the prime of life, able-bodied and hearty men. Had they remained at home in the works of peace, it is not likely that more than 500 of the number would have died. So then 14,500 lives may be set down at once to the account of the war. The wounded men are of course to thank the war, and that alone, for their smart and the life-long agony which they are called on to endure.
