Brett,
i still think it was a battle of attrition. Grant hammered away at Lee's army and when the numbers turned against him, he moved. Yes he was looking for open ground to fight Lee. Grants superior numbers would be more effective in open ground. Wasn't the infux into Lee's army militia from the carolina's and denuding the valley of troops?. If it was they were hardly suitable replacements for the veterans Lee had lost.
Dave , fair enough, and I don't want you (or anyone) to think I'm trying to argue in any other than a good-natured way. I don't particularly like confrontation and argument personally, so when disagreeing with anyone I try to do so as nicely as possible, if that even makes sense!

As someone with a math/computer science degree, I just really enjoy crunching the numbers sometimes, and this particular campaign seems to be one of the most misunderstood with regards to numbers (along with Antietam) in the entire Civil War. The frustrating thing is that the information to count Lee's men with a greater level of reliability has always been out there. Too many people, ESPECIALLY historians, have just accepted Early's (and others) claims with little to no critical analysis using documentable facts. This seems to finally be changing, as it also does with Antietam.
It's interesting that you should mention the quality of Lee's reinforcements in relations to Grant's. As someone who is extremely interested in the Siege of Petersburg (see the sig below), this is something which has always greatly interested me. Based on the admittedly little time I've been able to devote to that topic, the best way to answer that question is to look at the types of reinforcements the two armies were receiving.
Lee's reinforcements typically consisted of full brigades and even divisions which had fought together in at least one or more prior engagements prior to joining the fight in 1864.
Grant's reinforcements came in as individual newly formed regiments composed by 1864 of conscripts, bounty jumpers, draftees, or raw heavy artillerymen, who were then attached to veteran brigades worn down by years of service in the field. It made for somewhat odd unit cohesion, with these new and green regiments sometimes being larger than the brigades they were assigned to.
The Confederates tended to add small groups of men to their already existing regiments, surrounding new recruits with veterans, rather than the Union's preferred method of raising brand new units to appoint highly coveted positions to new Colonels, Lieutenant Colonels, and Majors.
Steven Newton, in Lost for the Cause: The Confederate Army in 1864, makes this specific point. Lee's reinforcements tended to be of higher quality than Grant's. The Richmond militia was counted by Newton in both his May 1, 1864 and June 30, 1864 estimates of Confederate strength. None of the 45,000 or so reinforcements Lee received from May 1-June 30 was militia, reserves, or local defense troops.
