Variable weather. Sunshine and rain. A large wagon train today takes its course towards Gettysburg. Lee's headquarters are still here. He keeps his troops in constant movement that it is hard to say what he is planning for his principal move. About 9 o'clock a large train of wagons are withdrawn from the direction of Harrisburg, and put on the line of march for Gettysburg. It took 4 hours for the line to pass here. The troops are busy destroying the Franklin Railroad at both North and South ends of the County. Along with sills of the road, they pile on all the fence they can find to heat and twist the rails. Another force of about 500 men have been sent to destroy the railroad depot and buildings, starting with the large turntable. It is so soundly built of iron castings, their fires had little effect on it. The engine house was pulled down after an immense amount of work. So they went from building to building, a senseless thing to do, as the structures were of no importance to us as we could not use them. I tried to reason with a nearby officer about the wanton destruction. Their answers are always the same, "This is in retaliation for your troops' work on the South, particularly Fredericksburg." Leaving this scene of destruction, which appears to be their last act. I went up to the belfry of the German Reformed Church to see if I could trace any damage to my farm, but could not, so much timberland intervening. You could mark the line of the railroad by the smoke of the burning ties. From what I can see, there is little damage to crops and grassland. This evening, there is much activity. Troops are withdrawn from all parts to march to Gettysburg. Reports that all ready there has been an engagement at Cashtown. Their cooks are busy preparing rations for the next few days.
