Fields of view are important to military operations. They will expose to the commander avenues of approach, fields of fire, ambush positions, naturally favorable ground, and conversely, naturally unfavorable ground. Sometimes a field of view can be deceptive, hiding certain features that might be used against the commander’s forces, or even deceiving him in thinking some ground is favorable when it is not.
Here is an image of the ‘Triangular Field on the west slope of Houck’s Ridge [Devils Den is on the east slope].
Note the apex of the triangle is at the top of the ridge, and the base at the bottom. The stone wall is where the 124th New York [Colonel A. van Horne Ellis’ Orange Blossoms from Orange County, New York] formed. The 99th Pennsylvania formed behind and to the left [south] of the “Orange Blossoms”.
Below is an image of the Slyder Farm from South Confederate Avenue. Note the rising stone wall of the Triangular Field on the left side of the image, and the small white object on top of the ridge is the 124th New York Monument.
Below is an image of Little Round Top from Emmitsburg Road north of the intersection with Confederate Avenue. This would be approximately where the right of General G. T. Anderson’s Georgia Brigade would be overlapped by the left of General Jerome Robertson Texas Brigade [with the 3rd Arkansas].
The view of Little Round Top from this area would be deceptive. It actually strikes the eye as one slope, gradually rising from the Triangular Field to the crest of Little Round Top. It show no sign of the Plum Run Valley, or of Devils Den, or, for that matter, anything else between the Triangular Field and the top of Little Round Top.
Confederate General William N. Pendleton wandered down this way, but perhaps a half mile north of here on the morning of July 2nd, and General Lee came down to a point about a quarter-mile north of here on the afternoon of July 2nd. Neither would have been able to see this view, but the solders in Hood’s Division could clearly see it. And at least for a while, they probably were fooled by it.
