Of the 2.3 million men listed in the Union armies, 70 % were under 23. Approximately 200,000 were 15 to 26, and records show that 25 were no older than 10.
In 1864, basic daily ration for a Union soldier was (in ounces): 20-flour, 2.56-dry beans, 1.6-green coffee, 2.4-sugar, .5 salt, and smaller amounts of pepper, soap, candles, and vinegar. They seldom received rations and had to forage.
In 1863 rations available for every 100 Confederate soldiers for 30 days consisted of 1/4 lb. of bacon, 18 oz. of flour, 10 lbs. of rice, and small amounts of peas and dried fruits— when it could be obtained.
In 1862 during Stonewall Jackson’s Shenandoah Valley campaign, he marched his force of 16,000 men over 600 miles in 35 days. Five major baffles were fought and four Union armies totaling 63,000 were defeated.
At the Battle of Fredericksburg in 1862, the Confederate trenches extended a distance of 7 miles. The troop density in these defensive works was 11,000 per mile.
At the battle of 1st Manassas, it has been estimated that between 8,000 and 10,000 bullets were fired for every man killed or wounded.
The heaviest numerical loss during any single battle was at Gettysburg, where 40,322 Americans were killed or wounded. Union losses were at 21 % and Confederate losses were at 3096- the largest number of Confederates hit in any battle. As General Lee was withdrawing his forces from Gettysburg his wagon train carrying just his wounded was over 18 miles long.
During May and June of 1864, the Union armies of the Potomac and the James lost 77,452 men— a greater number than Lee had in his entire army.
During the 4-year span over 600,000 Americans died: more than all the deaths, from of all the wars, we have fought in since then, combined.
In 1861, an infantry private was paid $13 a month. A colonel drew $95 a month and a brigadier general was paid $124 a month.
