On July 1, 1863, the men of Alfred Iverson's North Carolina Brigade had arrived at Gettysburg and were preparing to outflank the Union First Corps at Oak Hill. This spot was the northernmost point of Seminary Ridge. They were formed into their line of battle and advanced towards a line of trees about 300 yds. away. The Brigade was made up of the 5th, 12th, 20th, and 23rd North Carolina Infantries. To their left front was a low stone wall but they paid it no mind, they were confident in their success. They believed that they were about to crash through the woods and roll up the flank of the Yankees on the other side. Suddenly, a vast sheet of flame erupted from the stone wall. Some Federal soldiers,who were crouched down behind the wall, could not believe their good fortune at having an entire Confederate Brigade served up to them on a platter, so they burst over the top of the wall and let loose a withering volley at the unsuspecting rebels. Unfortunately for the Confederates, Iverson, their commander, had not deployed an advance line of skirmishers in order to prevent any surprises. Hundreds of North Carolinians fell in straight lines just as they had marched. In the days after the battle, they were buried in an unmarked mass grave, virtually in the same spots where they fell. For years after, the farmer who owned " Iverson's Pits " claimed that his wheat grew the tallest in that part of his field. Fighting on the Ridges by Dale Gallon.
