Although he sent Jenkins' Cavalry on a probing mission toward Harrisburg on Sunday, June 28th, Gen. Ewell proclaimed the day as one of rest. B. Tucker Lacy, a chaplain accompanying the corps, conducted two church services at the Barracks. At least one of his sermons concerned his recently deceased commander, Gen. "Stonewall Jackson." A committee of town clergymen asked Ewell for permission to include their usual prayer for President Lincoln, to which the gruff Confederate replied, "Pray for him. I'm sure he needs it."That Sunday, officers of Rodes' command enjoyed what would for many be their last real dinner, courtesy of stores left when the Federal garrison abandoned the post. General Ramseur wrote his wife that one morning during his stay, he had breakfasted on iced salmon. Enlisted personnel throughout the town made do . . . a soldier of the 12th Alabama Infantry sought his Sunday dinner at the National Hotel, recalling later that he "registered in the midst of an unfriendly and rough looking crowd of rough looking men. Had a poor dinner rather ungraciously served by a Dutchy looking young waitress..."
Ewell ordered a flag-raising ceremony at the Barracks on Sunday afternoon. Witnessed by most of the troops at the post, the 32d North Carolina Infantry Regiment raised the new Confederate national flag, the "Stars and Bars," as a band played. The Confederate presence at Carlisle and Carlisle Barracks was brief. The post was fair game for the invader, but strict instructions from General Lee forbade willful destruction of citizens' property. Four of Rodes' soldiers, caught disregarding this edict, were tied together and marched about the town to the tune of the "Rogue's March," with signs on their backs reading, "These men have disgraced themselves by pillaging women's gardens." The band noted that the onlookers were enjoying the spectacle entirely too much and changed their tune to "Yankee Doodle."
I believe you're asking about Route 34 south from Carlisle. Here are two Pennsylvania state historical markers which should help. There are several others for Rodes and Ewell between Carlisle and Gettysburg --

About five miles south of Carlisle Route 34 you will reach Holly Springs, then called Papertown. Continue south to Route 94, then called the Baltimore Pike, and pass over South Mountain. You will approach York Springs, then called Petersburg. In York Springs turn right on old U.S. 15 (SR 3001), also called Harrisburg Road, which leads more or less southwest to Heidlersburg. Rodes and his men camped there on the night of June 30th. There should be a marker on the road just north of Heidlersburg which reads,
Gen. Rodes' Confederate troops, returning from Carlisle to join Lee's army, camped here the night of June 30. The next morning, July 1, they marched west toward Biglerville, then known as Middletown.
Turn right (west) on Route 234 and drive to Biglerville. There Rodes turned south on Route 34 in obedience to new orders. From this point it's about nine miles south to Oak Hill, where Rodes stopped to deploy his division on the morning of July 1st. A marker on Her Ridge about three miles north of Gettysburg reads,
Gen. Rodes' Confederate troops marched down this road July 1, 1863, on their way from Carlisle. At this point they turned right along the ridge to Oak Hill, to attack the Union flank.
I hope you enjoy your travels! For those of you who enjoy 'what might have been,' consider how the Confederate attack might have progressed had Rodes cut a few miles off his journey and continued into Gettysburg on the Harrisburg Pike rather than the round-about route through Biglerville which placed his division on Oak Hill.
