"I have been so wholly engrossed with my work for the last week or I should have responded sooner to your question: 'Are you going?' If a kind Providence and President Lincoln will permit, I am. I am Captain of as good, and true a band of patriots as ever rallied under the star spangled banner."--Rufus R. Dawes.   A Full Blown Yankee of the Iron Brigade combines the personal experiences of Rufus R. Dawes with a history of the regiment in which he served. The Iron Brigade was the only all-Western brigade that fought in the eastern armies of the Union and was perhaps the most distinguished of the Federal brigades.   Dawes is credited with a keen sense of observation and a fresh and vivid style. Seldom absent from the field during his entire three-and-a-half-year term, he chronicled Second Bull Run, Antietam, Fredericksburg, Chan-cellorsville, Gettysburg, the Wilderness campaign, Cold Harbor, and the Petersburg lines. Perhaps most remarkable is the well-honed sense of humor he displayed about both the war and himself. Dawes's sophisticated account of significant military organizations and events improves our understanding of the epic of the Civil War.
