Meade's headquarters 1863 - 1865: Letters of Colonel Theodore Lyman
As a staff officer for General Meade, Lyman sheds some light on the barrage of orders received at the front at Pettersburg, page 167.
His reports also appear in Official Reports Petersburg
Page 242 describes the tension between Griffin and Crawford. "General Warren has a short leave, and General Crawford commands the Corps,
to the indignation, I presume, of old cocks like Griffin and Ayres; for C. was doctor in Fort Sumter, and thus got a sta, and thus is an old brigadier."
See page 328 for the Battle of Quaker road; 331 for White Oak Road;
334 for Five Forks. Chamberlain is not mentioned by name but belonged to Griffin's division and had the lead in these battles.
