In the Official Reports following the Gettysburg campaign, 1st Lieutenant John M. Gregory, Jr., Ordnance Officer of the Confederate Second Corps writes: "The artillery ammunition lately received from Richmond is packed in such miserably weak boxes that they are always bursting, and, in consequence, several boxes have been so much damaged as to render the ammunition entirely unserviceable. Besides, there is great danger of explosion in the wagons from the loose powder." Nevertheless, the only non-battle explosion of a caisson that I recall at Gettysburg was that of a Union battery moving quickly along a road on the edge of the battlefield.
