The entire fight occurred along the Cathaprin Road. The action began at Payte's Corner between the brigades of Rosser and Chapman's Brigade of Wilson's Division. Rosser routed Chapman at Craig's Meeting house. Wilson tried to sbabilize the battle at Corbin's Bridge with Bryan's Brigade, but Rosser routed that brigade too. Finally Davies Brigade of Gregg's 2nd Division stopped Rosser near Todd's Tavern. Rosser's Brigade did some of the best fighting of the war here but lost heavily.
Meanwhile there began a three day battle of Todd's Tavern. South of Todd's Tavern on the Brock Road at Alsop's Bridge Lomax's Brigade of Fitz Lee's Division fought Davies's brigade. At the end of the action the Confederates remained south of the Tavern and the Federals north.
The next day, May 6th Rosser continued his offensive up the Catharpin Road and was defeated by Custer's and Devin's brigades of Torbert's Division at the Rowe Farm. Rosser lost 125 men this day, making his total loss in two days well over 200 men.
Meanwhile the second day of the fight at Todd's Tavern occurred. The brigade of Gen. J. Irvin Gregg of Gregg's 2nd Division fought Wickham's Brigade of Fitz Lee's Division. The Federals broke off the fight when they retired northwards.
May 7th was the bloodiest day of the four day cavalry fight. With Torbert's Division Sheridan attacked Fitz Lee at Todd's Tavern, inflicing a lost of 200 on the Confederates and suffering heavily himself. However Sheridan abandoned the field and the Confederates still held the Brock road, the route to Spotsylvania Court House.
At the same time Hampton attacked Gregg with Gordon's NC Brigade on the Catharpin Road.
On May 8th Fitz Lee's Division fought a delaying action along the Brock Road and held up Sheridan's cavalry and Warren's infantry until Lee's infantry arrived at Spostsylvania Court House. Approaching from another direction Wilson's division briefly held the court house but was forced out by the Confederate I Corps.
These four days were among the bloodiest and most brilliant fought by Stuart's cavalry.
For further reading I recommend Gordon Rhea's book on the Wilderness and Michael Priest's two volume work on that same battle. Edwin Steere's book, The Wilderness Campaign also deals with these actions, as does an article by Ed Longacre for CWTI.
For more on the Confederate casualties I urge you to read a study written by Alfred Young in a back issue of North and South magazine, which I helped with.
