There is not much evidence, aside from this article, of Chamberlain being called "Joe." He was called Jack by college friends and Josh by some veterans later. His family continued to call him by his original first name Lawrence, even though he, (or his mother as he claims in his autobiography) reordered his names sometime before he entered college.

    In the headline it reads, "He tells of taking Petersburg and how he disregarded an order to win the victory" The reporter or editor who wrote the headline appears to have misinterpreted Chamberlain's quote from page 3,
"after the fight it was demonstrated that my refusal to obey the orders had really been the means of winning the victory." The journalist must not have realized they did not win that battle and mistook the phrase as an explanation of how they won the battle rather than a possible way they could have won it had the army charged together as Chamberlain wished.
    Without the help of tape recorders the quote could also not quite be word for word. Even though Chamberlain might not have seen the conclusion of the battle, there is no evidence that indicates he believed the battle had been won. In his later account he clearly states, "It was a disastrous day for our army and we were repulsed all along the line."*
    Even though Chamberlain's request was granted and orders issued for the whole army to charge, many brigades failed to do so and Chamberlain did not get all the support he was expecting. This is illustrated by a nervous Captain Webb in History of the 187th Regiment Pennsylvania Volunteer Infantry page 205, "What had become of the rest of our Division? Not in sight, surely."
    Aside from this account, The Hero of Gettysburg and the two speechs that touched on it, Reminiscences of Petersburg and Appomattox and Last Campaign of the War, Chamberlain rarely spoke of Petersburg publicly, his best account, "The Charge at Fort Hell," remained unpublished until 2004 when it appeared in the book, Chamberlain at Petersburg; by Dane Monroe Smith.

This article is mentioned in the History of the 150th Pa. and History of the 187th Pa.

The second article included clearly has some errors, Chamberlain not being a lawyer or Chief Justice.
