At the Battle of Chancellorsville the Stonewall Brigade suffered its highest number of casualties in any one engagement during the Civil War ("493 men, including the principal officers"). Despite the valiant efforts of the brigade shortness of the battle and sunset that
saved the day. Afterwards, the Brigade could not even muster a full regiment. Some similar stats, the ANV lost 22 % of their army, same as the 11th Corp.

The paper is by a student with a preconceived notion where he cherry picked quotes from diaries and publications to fit his narrative. Very well written, but poorly researched. The author quotes Gen Charles Winder about the forced marches, but it was actually Jackson who had to tell Winder to ease up on unnecessary discipline within his command. John O Casler "Four Years in the Stonewall Brigade" pgs 101-110. The author omits this as it does not fit the narrative. Loring was removed from command for not wanting to be stationed in what he believed to be an out of the way outpost. Who better than Jackson to know where to station men, he grew up in the area, not to mention that it was actually agreed upon to station Loring there by commanding general Johnston, in a letter to Jackson, Johnston writes that Jackson should let Loring seize Romney, while Jackson continued destroying the B&O RR. J.E. Johnston to TJJ Nov 23, 1861 Old Catalog Collection also in the OR. Loring did not like the assignment and went over his commanding officer's head. Yeah court martial, you betcha!
I can go on and on here and at one time did not really have any interest in SWJ, but through collecting Confederate headgear I found myself with an inordinate amount of Stonewall brigade hats and felt it was time to do some research not only into the brigade but the man who lent them his moniker.
I don't have all day, but can rip this paper apart with facts to an embarrassing point, yes Jackson faltered at Seven Days, largely due to not having slept for days as a result of Lee taking command and holding council for the war plans that he was to submit. Jackson was supposed to be in the Valley, but he very secretly moved his force to strike where needed around Richmond. He moved towards Richmond via train, but as he got closer deemed it prudent to go the rest of the way by horse as not to be recognized. Jackson even had Gen Whiting write out a pass for an unidentified Col to go through the lines; Jackson not wearing a coat with rank insignia was the officer. The federals were not to know that Jackson's Corps was in the vicinity. Jackson's best traits were secrecy, quickness, discipline and fierceness.
Did the men gripe early on, yes, but they griped about every commanding officer at some point, it's called being under arms.....Grant's men called him a butcher. Read any contemporary letter or diary after the valley campaign, Stonewall's men complained but adored him.
The idea that the generals whom he fought were inferior may be true, but they were better equipped and more numerous, not to mention, who was he to fight; the army to his front and often times rear.
This is like asking is LaBron is better than Jordan, we'll never know because they did not play against each other. The author pits Jackson against Burnside at Fredericksburg, pardon me but that was Lee against Burnside as the two army commanders, Jackson was a corps commander. He even calls Burnside inexperienced, excuse me, he was not a great general, but he had very similar experience as Jackson.
Now back to work as I could do this all day.......
