The author of this account, Augustus Buell claims he served as an orderly delivering messages to the artillery.
However, he was in reality not a cannoneer but a private in the 20th Regiment, New York Cavalry.
Buell would later write for the National Tribune and created this book from articles he wrote for that paper.
Although Buell would not arrive at Petersburg until December, long after Chamberlain was wounded, and even though he did not actually deliver orders to Chamberlain,
he describes him on page 322 as,
"a cold, unlovable man, very brave and all that, but not dashing either in appearance or manner.
He always reminded me of a professor of mathematics we had in college. Still, he was a gallant officer,
and had more than once been desperately wounded while leading his troops in the most deadly assaults."
General Griffin apparently did not share Buell's tastes, for as Gerrish relates in
The Blue and Grey
one page 405 when General Bartlett rode up in a new uniform he quipped,
"Well, Bartlett, when will the rest of the circus arrive?"
Page 229 - 233 describes the June 18th attack at Petersburg where Chamberlain was wounded. This description is also copied into the
History of the Fifth Massachusetts Battery, pg 877
Page 335 describes the battle of Quaker road where Battery B was under Chamberlain's command.
