Oct. 10th, the 24th Regiment of Michigan, Col. Henry Morrow, fresh from home, joins the brigade.
Cornelius Wheeler’s diaries

On my return to the army, I found Gen. McClellan had fulfilled his promise by assigning to my brigade a new western regiment- the 24th Michigan - Col. H. A. Morrow - and on the 16th I inspected it. In a letter, dated that day, I said: "I reviewed my new regiment this afternoon and was very much pleased with its appearance. From its bearing I have no doubt it will not be long before it will be a worthy member of the 'Black Hats.'"
