History of the Army of the Potomac
by J. H. Stine 1893

The description of the battle of Gettysburg, page 511, makes it seem that Vincent died right away, Chamberlain himself says in Through Blood and Fire at Gettysburg, "an answering volley scorched the very faces of the men and Vincent's soul went up in a chariot of fire.", the romantic way of writing in those days has caused this confusion, this may be why such famous historians as Shelby Foote mistakenly say Vincent was shot through the heart. For a clearer account of his death see, The 83rd Pennsylvania Regiment
On page 668 the author believes that if it wasn't for Chamberlain being wounded, he could have carried the works at Petersburg. It's quite a complement, but would take a long debate to argue if it were true. Here also he incorrectly states that Colonel Tilden of the 16th Maine took command when Chamberlain fell, it was actually Colonel Tilton of the 22nd Massachusetts.1 Tilton had commanded the First Brigade at Gettysburg but resumed command of his regiment when they were moved into the Second Brigade. It says something for Griffin's opinion of Chamberlain that he would give him the First Brigade over the head of Tilton who had once commanded it.
