The numbers multiply into new questions and ideas for how to think about three days in July, 1863. Count on it!

In early July, 1863, troops from General Robert E. Lee’s Army of Northern Virginia (the Confederates) met up with a patrol of Union cavalry on the outskirts of Gettysburg, Pennsylvania. Over the next three days, this encounter grew into a turning point of the Civil War. Lee’s forces battled against General Meade’s Army of the Potomac (the Union). When the battle was over, Lee’s army was defeated, and his aim of taking Civil War fight into the north had ended. The war would continue for another eighteen months, but Gettysburg changed the course of the conflict.

In all, 250 TONS of musket and rifle ammunition were used at the Battle of Gettysburg. If a car weighs about 2 tons, that’s the equivalent of about 125 cars! A male African Elephant weights about 3.5 tons, so that’s about 71.4 elephants!

On the Union side, it was reported that about 4 million rounds of ammunition were issued at the Battle of Gettysburg and that on the Confederate side, about 3 millions rounds were used.

That’s a total of over 7 MILLION rounds of ammunition, NOT including artillery fire. In comparison, McDonald’s sells about 6.5 million hamburgers each day.

One estimate is that it took 100 rounds to inflict one casualty at the Battle of Gettysburg.
