Does anyone have info on how long a Confederate corps with artillery and support wagons would stretch out on a road?
Thanks

Mickey,

See BATTLE IN THE CIVIL WAR by Paddy Griffith
Which gives good general back ground on the mechanics of Civil War armies.
p.8-9
march column 250 yds for 1000 men but at typical marching route step allow 500-750 yards for 1000 men. Following table on p.8
Infantry brigade 0.8 mile with baggage; 0.6 mile without.
Division 4 miles and 2.5 miles with/without
Corps 14 miles or 8 miles. (of course varies with size corps)
Cavalry div. 6 / 1 miles
Art’y batt 0.3 / 0.2 miles (remember batteries had guns plus two Caissons each and battery wagon)
Army HQ 3 miles
Army trains, reserve ammo & etc. 15 miles (but very variable)
Also see Appendix II p500 in
Wagner’s Organization and tactics; which is very detailed and complicated but much more contemporary to the period; although perhaps a bit idealized.

And the Classic by Jack Coggins ARMS AND EQUIPMENT OF THE CIVIL WAR has good info and GREAT illustrations.

As a practical matter road space of units and trains were a very critical consideration. And always a trade off of keeping units near their trains vs keeping combat units closed up.

Great question IMHO.

Mickey

In Coggins a gun is 16 yds and caisson is 14 yds and batty wagon & forge each 14 yds
4 gun batt = 4 x 16 + 8 x 14 + 2 x 14 = 204 yds allow double for marching dist at least about ¼ miles per 4 gun batty.
Coggins p 64-65

Gentlemen
Very interesting and informative

On The morning of July 2 my great-great grandfather's unit the 7th NJ was marching with its brigade up the Emmittsburg rd. In addition to his brigade there was another brigade, two batteries and the III Corps train. Until I read these post I never gave a thought to the length of the column.

Good stuff

John Hayward,
Thanks interesting personal connection.
My own Great-Great Grandfather David served in Armistead’s brigade in 1862 and again in 1864 but he was not at Gettysburg, but his cousins and neighbors were in the 38th Va and 53rd Va. Units from Pittsylvania County. One was wounded and another wounded and prisoner in the 3rd day attack. On the 2nd Picketts Div marched from Chambersburg arriving near the Battlefield about 2:30 after 23 mile march.
Best wishes to you and yours, Mike Collie.
