Graphical Details (continued) 

All the units displayed in the APP are scaled to size with respect to the underlying map. Each unit Disposition (described on the preceding page) has an associated algorithm that determines the unit's scale length. The frontal dimension, for Infantry and Cavalry units, is to scale, while the depth or thickness of each graphic is not to scale since doing so would make the units too thin and difficult to see. For Artillery units the length and depth are both to scale, the sizing algorithm including all the battery components (total area occupied by gun, caisson, limbers, horses, etc.)

The Pop-up Window (described on the preceding page) displays the length of line or column for each unit. In the case of online artillery batterys, battery sections or individual guns, the "length" is the unit's frontal dimension. The math behind these calculated dimensions is shown below. 

• Infantry Dispositions -
  • Line of Battle, Organized Retreat, Charging Line of Battle - # of men, divided by two¹, times 1.5 ft², times 85%³, times 100%⁴.
    • ¹Two ranks or lines of men
    • ²Each man "shoulder to shoulder, elbows touching", 18-inches (default value and can be changed).
    • ³15% of the deployed Regiment was not on the front line; comprised of 7 file closers per company (4%), plus one reserve company (10%) plus 1% senior officers, quartermaster, surgeon, aides & orderlys.
    • ⁴Factor reserved for future use. 
  • Line of March - # of men, divided by four⁵, times 3 ft⁶.
    • ⁵Column comprised of ranks or rows of men, four men per rank.
    • ⁶Three feet of distance between the front of the man in and the front of the man in the next rank.
  • Chaotic Retreat - Within the APP, the historical artistic interpretation of this type of retreat is that the total of active men plus 25% of the cumulative casualties (to account for "walking wounded" within the retreat mix) are multiplied by a square footage variable such that the retreating "mass" (graphical represented as an oval) is sized to contain soldiers randomly spaced from "side-by-side" to 8-10 feet apart.
  • Skirmishers - # of men, times a "variable" # of feet (btwn 3 - 15 ft. depending on deployment).
  • Post Fighting/Bivouacked - Similar to Chaotic Retreat, the scale sized graphic, in this case a square, this calculated by multiplying the active number of men times a square footage factor consistent with men 5 feet apart (25sqft area)..

Unit Dimensions  

Union units are BLUE or LIGHT BLUE, where Light Blue indicates that casualties have occured during that Tick.

Confederate units are RED or ORANGE, where Orange indicates that casualties have occured during that Tick.

Unit  Colors 

• While the Official Reports of the battle document the number of reported casualties by unit; killed, wounded and missing, but no such reports could contain specific numbers itemizing when and where the casualties occured. The creators of the APP, therefore, used historical artistic license to apportion the number of casualties to particular instances during the battle animation.
  • For the Ticks where the casualties are apportioned the color of the units will change as noted above. 
  • The apportioned number of casualties will appear in the unit's Pop-up window (described previously).
• The number of accumulated casualties progressively reduces the number of men active in the unit, which impacts the length of the line or column.
  • The scale length of the line will not necessarily change at that point in time that casualties "occur".
  • The APP uses a "Reorganize" designation at selected Ticks, to shrink the line, emulating the reformation or closing of ranks ordered by officers at opportune times during an engagement.

Casualties 

• Cavalry Disposition -
  • Dismounted Line of Battle -  # of men¹, times 5 ft², times 74%³.
    • ¹Single line of men.
    • ²Five feet spacing between men (default value and can be changed).
    • ³26% of the deployed Regiment was not on the front line; one man in every 4 (25%) was designated to hold horses in the rear (APP does not depict these men or horses); plus 1% senior officers, quartermaster, surgeon, aides & orderlys.
  • Mounted Column - # of men, divided by four⁴, times 12 ft⁵.
    • ⁴Column comprised of ranks or rows of men on horseback, four men per rank.
    • ⁵ Twelve of distance between the front of the rider in one rank to the front of the rider in the next rank (9' per horse + 3' spacing between each horse). 
  •  Skirmishers - # of men, times a "varriable" # of feet (btwn 3 - 15 ft. depending on deployment).

• Artillery Dispositions -
  • Online - Each hollow rectangle of a battery represents the area (acreage) occupied by one gun of that battery.
    • The gun (not actually shown within the graphic) is assumed to be at the end opposite the name of the unit. 
    • The scale size is 14 yards wide, by 47 yards deep; the military manual size to accommodate the gun, horses, limbers and caissons.
  • Limbered - Each solid line represent the length of the column for a single artillery piece.
    • The movement direction of the gun column, when the animation is not active, is implied by the position of the battery name, which is at or near the front of the limbered battery column.
    • The scale side of each gun is 8 feet wide by 90 feet long, and includes the area (acreage) occupied the horse teams, gun, limbers and caissons.
  • Prolonge - A hybrid of the Online dispostion with the same graphical characteristics and historical artistic license applied.
    • The scale size is 7 yards wide, by 30 yards deep; depicting the area (acreage) occupied as both horses and/or men pull an un-limbered gun toward the rear, with associated caissons, limbers and horses also retreating with that area.
