We see this:
And this (full size so you can pick out the details):
Notice the maneuvering handspike on the lower left. Those details show up on the right hand side of this photo:
Here’s another view of that ammunition chest:
The accouterments hanging on the earthworks in front of the wheel:
Having established the Wiards position on the second parallel as just to the left of the Napoleons, let’s look at the guns themselves. A great study of the Wiard Guns and their advanced, if non-standard, carriages.
For those unfamiliar, the trail of the carriage meets the axle below and not on top as with a standard Army field carriage. The placement of the trunnions on a high, arching cheek allowed for greater elevation – up to 35°. The rear sight hangs from a seat on the back of the breech.
The crew is loading the other gun in the pair. From this angle, we also see the wedges, a feature that counteracted shrinkage of the wooden wheel.
The gun crew wears an assortment of hats. These fellows were part of Lieutenant Paul Berchmire’s Battery B, 3rd New York Light Artillery. Aside from the hats, there’s a bit of contrast among those men.
Some look like they have yet to shave for the first time. Others seem to have avoided razors for years.
However, I’d point out my placement of these two photographs stands at odds with this photograph:
The right pair of howitzers seen here occupy positions used by those Wiard guns in the photo above. See, again, the cut from Major Thomas Brooks’ map, focusing on the “How. Battery” in front of Battery Brown:
But I think we are looking at the same section of the second parallel, but at different times. Brooks’ journal entry for August 6, 1863 provides a clue:
Made repairs in defensive howitzer battery on the right of second parallel. Two Wiard field guns now in position there have proven very destructive to platforms and embrasures; more so than any field guns which have come under my observation.
Perhaps some of the debris seen in the howitzer battery photo was the result of those “destructive” Wiards.
At any rate, if my figuring is correct, when the engineers first established the second parallel, two Napoleons and two Wiards anchored the line on the right. Later the Napoleons went to positions further to the left, as indicated on Brooks’ map. The Wiards likewise moved to the left, with one going on the far side of Battery Kearny. That Wiard gun position had embrasures for firing on both Battery Wagner and Battery Gregg – an arrangement not seen in the Wiard gun photo above.
So three photos. Two taken early in the siege. One taken later. All of the same general area.
