The only reason I asked you about the two brief paragraphs Barnard wrote on Seven Pines was that you had already done a deep-dive down to the bottom level (see your post at #8 in this thread). You first reaction was to count regiments and talk about a specific bridge, not to try to see what Barnard might be pointing you at. You are saying he is wrong because he could not get the Sixth Corps across the river. He is telling you something completely different, that the repulse on May 31 should have been followed up immediately: "Had it been so, there would have been no resistance to overcome to bring over our right wing." You jumped to attacking something he had not said.
Though Barnard's analysis - where he talks about his reasoning - means that regiment counting at least is completely valid. Barnard's argument with respect to why it should have been followed up includes that the Confederates were exhausted, but looking at who suffered the casualties indicates that most of their units had suffered basically no casualties.
And it's not just "a specific bridge" but the existence of bridges at all - the bridge Sumner crossed by collapsed after his infantry was over, at least to my understanding.
What this means, at least if I follow what's being said by Barnard and your interpretation thereof, is that Barnard's analysis of post-Seven Pines is:
1) following up the attack
- The repulse on May 31 should have been followed up immediately.
- This is
because the enemy had exhausted themselves and run out of available resources.
- We didn't know that at the time, but we do now, which is why I say this now instead of then.
2) bringing over the right wing
- had we done this (i.e. repulsed the enemy) then we would have been able to bring over the right wing without any problems ("no resistance to overcome").
Here's my view of that...
- by regiment counting, we can determine that most of the force that the Confederates had (in terms of regiments) was not exhausted. This is a point directly against Barnard's chain of logic - the "what we know now" aspect of how exhausted the Confederates were is based on incorrect information.
- the fighting continued until darkness, and in fact resumed on June 1 with a renewed Confederate attack (Birney for example only gets involved on June 1, and Richardson's division is driven back before rallying). So clearly the Confederates were not fought out on May 31 since they were able to launch attacks on June 1.
- The Confederates withdrew to captured earthworks, with some reluctance, midmorning on June 1.
So immediately it seems clear that the picture of the Confederates as easily counterattacked after the repulse on May 31 is not a full picture of the situation. They were still attacking early on June 1 and then withdrew to captured earthworks.
This then means that an immediate counterattack by the Union forces south of the river would have been essentially a "hasty" attack against an enemy who was still fit to fight. If that's late on the 31st then the units which would be being attacked would in some cases actually be the ones who attacked the next day, so clearly still had some fight in them, on top of the attack being a night attack; if that's early on the 1st of June then either it runs into the Confederate attack (result, a general melee) or it comes after that.
The best case is if it hits the Confederates during the period when they're withdrawing into the captured earthworks, but to plan this in advance would be quite difficult given how long attacks take to plan out - on the 31st the Confederate attack had been five hours late for example!
In addition to that, the bridge problem still exists - there weren't
any viable bridges on the morning of the 1st except the rail bridge, a day's march away. Now perhaps what Barnard means by "no resistance" to being able to bring over the right wing is that they could have sent 6th Corps around the wrong way, or perhaps he means that they could have crossed 6th Corps in the next few days, but neither of those is dependent on whether or not the enemy had been repulsed (while Barnard mentions the conditional).
Alternatively he could mean that pushing the enemy back would make it possible to properly repair New Bridge, but it's my understanding that the engineers erected trestles around New Bridge over the course of the 1st June (including some of the work being done in the morning, before the Confederate pull-back). So there apparently wasn't anything about enemy positions on the 1st of June preventing bridging
work being done in that location, it was just that it wasn't carried to a successful conclusion.
A final possibility is that he's thinking in terms of pushing the enemy away from the Chickahominy entirely, and permitting the Union forces north of the river to cross by the existing crossing places by making sure they weren't defended. This would satisfy the conditional, but the scale of the advance required is large - the Mechanicsville Bridge is about three miles further west than the New Bridge, and it's about a mile past Fort Johnston, so if Barnard is arguing this then he's arguing the ability to take Fort Johnston.
What I suspect is going on, and I invite you to consider this and see how it holds up, is that in writing this months later Barnard has been
misinformed as to the precise situation on the Confederate side of the lines on the end of the 31st May and beginning of 1st June, and is under the impression that the Confederates were more defeated and vulnerable than they in fact were.
I suspect he did think that the Confederates were in such a state that they could be repulsed (and forced not merely out of works but out of forts) by a firm offensive even by the also-disrupted Union troops, and that this mistaken impression of Barnard's was formed:
1) partly by the idea that Confederate forces in Richmond were smaller in number than the truth (so the number of troops engaged would form a higher % of the number of troops available, i.e. he thinks that all their units were in heavy fighting - as he says - rather than only some)
and
2) partly by sensationalist news reporting exaggerating the scale of Confederate disruption (at least at the brigade level and below).
It's not like the Confederates had been routed from the field; they'd attacked and gained ground, been stopped, and then some of the force had been repulsed by a counter-attack around dusk but other attacking units had (later, meaning on the 1st) voluntarily withdrawn back over some of the ground they'd taken. There were also units which hadn't really fought at all.
Certainly the Confederates are weaker than if they hadn't had the battle, but whether that rises to the point of being able to rout them back into Richmond as Barnard suggests is a substantially higher bar.
