MEXICAN WAR.
There was a similar waste of life among our troops in the Mexican War. There is no published record of the number of the sick, nor of their diseases. But the letters of General Scott and General Taylor to the Secretary of War show that the loss of effective force in our army was at times very great by sickness in that war.
General Scott wrote:—
"Puebla, July 25, 1847.
"May 30, the number of sick here was 1,017, of effectives 5,820."
"Since the arrival of General Pillow, we have effectives (rank and file) 8,061, sick 2,215, beside 87 officers under the latter head."[31]
Again:—
"Mexico, Dec. 5,1847.
"The force at Chapultepec fit for duty is only about 6,000, rank and file; the number of sick, exclusive of officers, being 2,041."[32]
According to these statements, the proportions of the sick were 17.4 to 27.4 and 24.7 per cent of all in these corps at the times specified.
General Taylor wrote:—
"Camp near Monterey, July 27,1847.
"Great sickness and mortality have prevailed among the volunteer troops in front of Saltillo."[33]
August 10th, he said, that "nearly 23 per cent, of the force present was disabled by disease."
The official reports show only the number that died, but make no distinction as to causes of death, except to separate the deaths from wounds received in battle from those from other causes.
During that war, 100,454 men were sent to Mexico from the United States. They were enlisted for various periods, but served, on an average, thirteen months and one day each, making a total of 109,104 years of military service rendered by our soldiers in that war. The total loss of these men was 1,549 killed in battle or died of wounds, 10,986 died from diseases, making 12,535 deaths. Besides these, 12,252 were discharged for disability. The mortality from disease was almost equal to the annual rate of 11 per cent., which is about ten times as great as that of men in ordinary civil life at home.
