Right. Out of those, King is the only one he wanted to take the Peninsula but wasnt allowed.
Yeah. Some of those didn't come right away, but if we're talking about over the course of the campaign, the majority are part of the Seven Days campaign and some even make it to the Peninsula days.
Ok. Just seems to me that since you included "Defenses Upper Potomac" with those left behind why not include Slocum and Sigel? or Banks and Shields in spring of 62? Its just not clear to me why you are slicing things in the way you are.
"Defenses Upper Potomac" seems to relate to the issue of Washington's defenses (or at least "tied up as garrison"), but I'm not sure on Sigel and Slocum - their situation seems comparable to Banks in '62 in regards to "in the field, not necessarily with the main army".
I'm open to whatever interpretation is most fair and consistent if you think mine isn't there
Have to disagree with you here, even if Sickles remains in the spot he was placed, which actually was not where Meade wanted him anyhow, he should have been a little farther back than where he was camped the night before. Anyhow, V Corps was 1100 yards behind him as a reserve, Sickles would only have a mile long line to cover instead of the 2 miles he chose by moving up but he still would have needed the additional 11000 V corps troops. II Corps was originaly on the left but moved to the center as it could be sent either left or right, in which in this case they were sent to the left to help bail Sickles out. I am sure some of those troops would have still been sent to the left even if Sickles remains in place. The only thing I will say you are correct is the XII Corps wouldn't have had to go to the rescue. III Corps, V Corps, and half of II Corps would have given Sickles about 27,000 infantry, about 31-32k if all of II Corps shifts.
Had Sickles been in position as ordered, he would have had Caldwell's division (1st Division, 2nd Corps) on one flank and the other resting on LRT .
http://edtech2.boisestate.edu/dougwolfe/502/vtour/wheat.html The map admittedly does not show Sickles's intended position, but it does show the rest of the Union line.
Had Sickles not tried to have a salient without support on its flanks, there would not have been the need to send 2nd Corps to support Sickles because they would already be in a position to support, and 5th Corps would not have had to send four brigades to do what was supposed to be the responsibility of Sickles's corps.
Looking solely at the forces of his own corps, Sickles had about 9,900 infantry.
Hood and McLaws had around 13,735 infantry.
There is no reason Sickles needs to have such substantial reinforcements from Fifth Corps except spreading his forces too thinly in a position with its flanks exposed and disregarding important ground (which occupied four of eight Fifth Corps brigades).
Might it be necessary to reinforce LRT or any other specific point? Yes, defensive lines sometimes need back up. But not for the line on the whole.
