Their point men rose from fields of grain to pepper with gunshot Union regulars and militiamen defending the town from recently dug trenches.
The impatient Rebels were intent on reaching the mile-long covered bridge spanning the Susquehanna River. If they could take the bridge, this unit of Robert E. Lee's Army could take Harrisburg from the rear or march on to Philadelphia.
Seeing the Yankees in trenches, the attackers unlimbered four cannons from W.A. Tanner's Courtney (Virginia) battery.
James Kerr Smith, a Hellam Street resident, counted 49 shots, both solid shot and exploding shell. Gordon's boss, Gen. Jubal Early, later wrote that the Union defenders started running on the third shot, suggesting a shorter bombardment.
Whatever the number, many enemy shells fell into the town of Wrightsville filled with civilian men, women and children.
One of the shells found its mark.
A fighting man with a black militia unit from Columbia was one of those in the Union trenches.
His unit had been steadfastly digging trenches before the Confederate approach. When the gray-clad soldiers came within sight, his unit exchanged their shovels for rifles.
At some point in the bombardment, one of the Confederate shells struck the man, decapitating him. His identity is unknown today.
Other shells barely missed civilians.
Amanda Beaverson, crossing a street with her two children, escaped the explosion of a nearby shell without injuries.
About 150 years later and just a couple of miles away, a crowd gathered to commemorate another Civil War soldier.
According to tradition, he was identified as a Confederate soldier when his body was discovered on the bank of the river.
Historians don't know his name or the Confederate unit he served with.
The Confederates were along the river in York Haven and other points upstream. Did his body wash downstream? Was he one of Gordon's scouts, looking for a ford across the Susquehanna? Was he part of Gordon's brigade, who had strayed or deserted?
One way or another, his burial place has been marked over the years. Now, a new monument marks the spot of this unknown Confederate, and those gathered were there last weekend for the dedication.
So we have an unknown enemy soldier, an invader of our soil, who is remembered today with a marker. His kinsmen in uniform blew the head off of a defender and fired on a town full of civilians. On the march, they stole horses, terrorized women and children and destroyed crops.
And then not far away, we have a site where an unknown friendly soldier in blue lost his life in defense of his home and country.
The site where he died, which could be identified within a couple of yards, is forgotten today.
There's a lesson here as we contemplate the 150th anniversary of the Battle of Gettysburg.
This is a time for serious contemplation about a most difficult moment in our history.
At the heart of this struggle rested ingrained racism that swirled beneath the efforts of many Southern generals on horses and fighting men in butternut and gray on the march.
The Rebels were fighting for a racist cause that at the end of the day sought to keep black men, women and children enslaved.
Slavery was a racial issue because the only form of chattel slavery in the South or North was black-only bondage.
In a border county like York, we were unduly exposed to Southern views about slavery before, during and after the Civil War. The many Confederate flags around the county today testify to that.
We should ensure in this 150th anniversary that we don't get caught up in the glamour of Confederate generals with plumed hats and the Southern-inspired pageantry that is often applied to this bloody war. To paraphrase Robert E. Lee, this was a terrible war - so, 150 years later, we should not grow too fond of it.
The Confederates, after 20 miles of marching that late-June Sunday in 1863, lost the footrace to the bridge.
By the time they arrived at the bridgehead, the span was aflame.
Union commanders had tried to drop a span into the river and save the bridge. That mining did not dislodge the sturdy wooden span, so the Union officers went to Plan B - burn the structure and allow the river to keep Gordon's men at bay.
The fire spread to Wrightsville, and the Confederates, in turn, worked to keep the fire at bay.
Some expressed gratitude to the makeshift firefighting unit clad in gray that kept Wrightsville from burning mostly to the ground.
But Gordon's men were under orders not to burn or destroy civilian property, so their act was a protection against the wrath of Robert E. Lee.
The next day, Gordon ordered a countermarch to York - a march that would eventually take them to the battlefields of Gettysburg.
When the Southern men cleared out, the body of the black fighting man was found in the trench.
Maybe some day, a researcher will uncover the identity of this brave man, whose death preceded the sacrifices of the 54th Massachusetts at Fort Wagner, S.C., featured in the film "Glory."
This unknown soldier should be honored with a marker on or near the spot where he fell, defending his country against a vicious enemy attack.
