Col. William W. Jennings commanded the 26th Pennsylvania Volunteer Militia, the regiment sent to defend Gettysburg on June 23 -- he and his men were delayed from reaching the town because of a cow - train accident west of New Oxford. Jennings sent a vanguard to Gettysburg, where York's Major Granville O. Haller ordered them west of town to defend the turnpike near the Marsh Creek crossing. Jennings' regiment arrived on the morning of June 26, marched to Marsh Creek, and by mid-afternoon was in full retreat after the approach of Confederates of Brig. Gen. John B. Gordon's expeditionary force. Not long afterward, Jennings' main body was shattered by the 17th Virginia Cavalry at Witmer Farm northeast of Gettysburg and forced to march to Harrisburg. Some of his men escaped the twin fiascos and made into York County, where eventually they took part in the defense of the Columbia-Wrightsville Bridge.
Haller and Jennings, political opposites, blamed each other for the loss of Gettysburg to the Rebels.
So, who was William Wesley Jennings, who played an important role in the early part of the Union defense of Adams and York counties???
