American Civil War Game Club (ACWGC)

My impression is that the wagons in the game just represent the ammo wagons which were probably few in number. The actual divisional and Corps trains were quite large. At Gettysburg Longstreet's Corps (Anderson and Johnson may have also waited on them) was delayed because Longstreet decided to allow the 3rd Corps wagon trains to pass down the pike first. I believe they were something like seven miles long but I would have to go find the book that described it to be sure of the timing around it. They stopped on the west side of South Mountain but their blocking of the road probably did more to decide the battle on the first day than any other command decision made. According to the reference Longstreet was the one who made the decision. Lee had apparently already left for the front.

A quick search yielded for the Union Army:
The American Civil War and the origins of modern warfare By Edward Hagerman
<blockquote id="quote"><font size="3" face="book antiqua" id="quote">quote:<hr height="1" noshade id="quote">...McClellan estimated his strength for the Maryland campaign to be 122,000 aggregate present.
Meigs estimated the effective strength of the army at 130,000. Meigs worked out detailed wagon statistics of twenty-nine wagons per 1000 men, which adjusted to McClellan's estimate of his numbers, increases to thirty-one wagons per 1000 men...

...For a supplementary description of the details of how the trains followed the columns, parked behind the lines, and ran material to the front as needed, see the report of Lt Col C W Tolles, chief quartermaster, XI Corps, Army of the Potomac, for the Chancellorsville campaign. <hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">
For the ANV:
<blockquote id="quote"><font size="3" face="book antiqua" id="quote">quote:<hr height="1" noshade id="quote">...The first record of Confederate field transportation standards begins in 1863....This document contains the transportation standards set for the Army of North Virginia from April, 1863, to April, 1864, and for the Army of Tennessee from August. 1863, to November, 1864.
...The order of April 20, 1863 set a standard that included: one wagon per 100 men present; one wagon for ordnance per regiment, which calculates at approximately one per 500 men in accordance with the reduced size of regiments varying from 375 to 500 men; one wagon per 375 men for the reserve ordnance train; one ambulance wagon per 300 men. This adds up to a total of approximately thirty-four wagons per 1000 men including the reserve train...
I am also speculating that the one reference to a reserve train that does not designate it to be an ordnance train in fact refers to the reserve ordnance train, since all other reference to the reserve is to the ordnance train...
...Another explanation, of course, is a sloppy compilation of general orders.<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">

Finally from another site:

<blockquote id="quote"><font size="3" face="book antiqua" id="quote">quote:<hr height="1" noshade id="quote">http://www.15thnewyorkcavalry.org/the_quartermaster.htm
The Federal Army organization provided for a Chief Quartermaster for each Army with the rank of Colonel. For each Corps within an Army was a Chief Quartermaster with the rank of Lieutenant Colonel. Each Division within a Corps had a Divisional Quartermaster with the rank of Major. Each Brigade within a Division had a Quartermaster with the rank of Captain. Finally, each Regiment within a Brigade had a Regimental Quartermaster with the rank of Lieutenant. All of these had staffs and assistants. The Regimental Quartermaster had, under his direction, a Regimental Quartermaster Sergeant charged with the responsibility of storing and transporting the property assigned to the Regimental Quartermaster for the Regiment.

Beginning in 1862, each Company of Cavalry was authorized a Company Quartermaster Sergeant. The Company Quartermaster Sergeant was under the direction of the Company Commander and the First Sergeant. He was responsible for the Company wagon and all the property it contained, including the tents, the Company mess gear, the Company desk, the Company library, the ordnance, the subsistence provisions, and the Company tools (blacksmith, carpenter, gunsmith, etc.). He was further charged with overseeing the camp set-up of the tents and picket lines. He inspected the Company horses and mules, and reported any problems to the Veterinary Surgeon of the Regiment. He was also responsible for acquiring the fuel (wood), forage for the horses, and straw for bedding. These would normally be drawn from the supplies of the Regimental Quartermaster, along with replacements for uniforms and equipment. When not available, the Company Quartermaster Sergeant was responsible for forage parties to acquire them. The Company Quartermaster Sergeant was required to sign for the uniforms and equipment that were in his custody. Similarly, before disbursing these items to a soldier, he required a signature of receipt, countersigned by an officer. The rank of Company Quartermaster Sergeant was not a command position, although he was required to know the drills, and the duties and responsibilities of the line NCO’s. He was a member of the Company, and his name was recorded next after the First Sergeant on the Company rolls. During combat, his place was safeguarding the Company wagon and its supplies. He was generally required to fight only in defense of the Company property. In an extreme emergency, he could be used to replace a fallen line NCO, but this was extremely rare. The wagons were driven by Teamsters, who were usually members of the Company. Additionally, each Cavalry Company was authorized a Wagoner with the rank of Corporal. The Company Quartermaster Sergeant was designated by his chevrons which were three stripes with a single tie in worsted. This was an unofficial chevron that was not incorporated into United States Military regulations until 1866. It was, however, the standard chevron of Volunteer Cavalry Companies since 1862. <hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">
I find all this interesting because of so many scenarios that the Confederates are in short supply.
I expect that there was no great difference in organization because most high commanders of large forces for both sides were West Point graduates and the patterns of organizations and doctrines were U.S. Army originated.
