If Jacob was present at Gettysburg, he was very fortunate to have come through untouched. In that battle on 2 July 1863, the 8th South Carolina was, by an unfortunate error in command, ordered to change direction as it approached the Union batteries near and east of the Peach Orchard. As a result the regiment received a devastating fire at close range from the 15th New York, and 5th and 9th Massachusetts batteries. Thirteen identified dead from the 8th South Carolina were buried as they fell in the depression just north of George Rose's stone barn. Close by were another 40-50 unmarked graves from the brigade. The barrage effectively knocked the 8th South Carolina out of the fight before they could engage their foe. First Lieutenant Hyman Werthiem and Lieutenant P. B. Langford of Company E were killed in that location, while Lieutenant Theodore F. Malloy came out unscathed and was promoted Captain of the company on 20 July 1863.
