So against their better judgement the Confederates of Steuart’s brigade made at least some effort to level their existing line. How much of an effort? Like in most military units it probably depended on how much the company level officers made the men do. The refused line out about 135 yards from the apex is well leveled, and if there ever were traverses they do not remain. Closer into the apex there are substantial works and traverses still in existence. While possible that these were from later occupation by the Federals, I think it more likely that the Confederates made only a pretense of leveling them as their new line would have, as McHenry Howard said, have covered them with a enfilade fire.
But this only covers a short section of the line running out to and beyond the Landram House. This heavily traversed line still exists in relatively good shape as it runs either just inside the wood line or through the woods.
NPS Historian Ralph Happel answered that question for us when he was preparing the background information for the Spotsylvania base map in 1948.
“The north-south trench line running past the Landram House is Federal and should be shown as such, although both Duane and Michler show it as Confederate. Hotchkiss, the Confederate topographical engineer shows no trenches as Confederate outside the salient area. Furthermore, documentary evidence brings out the fact that this line was dug by Birney’s division of Hancock’s Federal Corps and occupied May 15-18. These troops faced West and then constituted the right of the Federal Army. The opposing forces had shifted South and east; no Federal line West of the Landram House was then held , and the Confederates had abandoned the Mule Shoe.”
So there you have it. Like so many things about Spotsylvania its a bit more complex than it appears on the surface. And infinitely more interesting.
