I passed through Gettysburg a few weeks back, coming into town from the east side. I have rarely spent any time at the East Field, scene of the great cavalry clash on July 3, 1863. It was here that Gregg's cavalry division attempted to blunt Stuart's effort to wreak havoc on the Federal rear. In this regard, Gregg was largely successful.
It should be noted that, to great extent, the mythology that surrounds one George Armstrong Custer found its origins here, on this field. It was one of the rare instances where two great cavalry forces clashed absent any infantry, a great swirling mass of horsemen, sabers drawn, repeatedly charging and countercharging. Custer, gleefully leading his brigade of Michiganders, is said to have rallied one of his countercharges with the cry "Come on, you Wolverines!" as they plunged headlong into the Confederate horsemen. He, unlike many of his men, would emerge unscathed.
In 1889, some thirteen years after his death on a hill in the Montana Territory, Michigan erected a monument at the site of Custer's charge here in Pennsylvania. It's one of the few markers on this part of the field, sitting on a slight rise along Gregg Avenue. Worth a visit, should one get there.
