The diary of John C. Van Duzer, found in the Andre De Coppet Collection, Manuscript Collection, Princeton University Library in New Jersey, has this entry recorded during Sherman's March to the Sea: Pooler, Georgia, 9 December 1864: "Four torpedoes laid in a line across the roads. The two center ones had exploded, leaving the two outside ones to do their work. A Colonel on General Blair's staff and the Adjutant of the 1st Alabama Cavalry came up and commenced looking for the other two by pushing the loose dirt from the top. The Colonel uncovered his, but the Adjutant, not finding his as close to the top of the ground as the Colonel had done, supposed there was none there and commenced stepping around carelessly, when all at once it exploded. I stood within eight feet of him and the Colonel still nearer. As soon as the smoke cleared up we found the poor fellow's foot entirely shot off, a piece of shell going in at the heel and coming up at the knee. Rebel prisoners were immediately sent for and compelled to dig up these machines." A little further on, Van Duzer describes the approach to Fort McAllister "... our boys suffered much from torpedoes laid across the roads ... [Federal] killed and wounded by torpedoes does not exceed 90" [men]
