Pennsylvania College (now Gettysburg College) Prof. Michael Jacobs' weather notes from the Battle of Gettysburg were mentioned in a July 2 article on AccuWeather.
The Battle of Gettysburg is said to be the bloodiest battle of the American Civil War. Fought in Gettysburg, Pa., July 1 through 3 in 1863, historians put the number of causalities and missing Union and Confederate soldiers at 46,286. Bayonets, rifled muskets, cannons and infections all contributed to the carnage that took place 150 years ago today. The weather, however, created some causalities as well.
A Gettysburg man by the name of Rev. Dr. Michael Jacobs, a math professor at what was then called Pennsylvania College, had a strong interest in weather and recorded his observations three times a day, every day, even during the battle. As a result, the "Meteorology of the Battle", was published, and it gives very specific details on the weather at the Battle of Gettysburg and the role it may have played in battle.
