| 1862/10/04 | George Benedict, 12th Regiment: 'yesterday afternoon was rendered memorable by our first knapsack drill. The orders were for a review of the regiment, fully equipped, with knapsacks packed. The overcoat was accordingly folded and placed within the knapsack; the change of underclothing, socks, etc., ditto; and the woolen blankets rolled tightly within the rubber blanket and then strapped on the top. The whole concern, with the straps, weighs on an average about thirty-five pounds, and there goes science, let me tell you, to the production of a skillfully packed knapsack.' (Army Life) |
| 1862/10/05 | George Benedict, 12th Regiment: 'the review by Gov. Holbrook and inspection yesterday, was not as tedious as we expected. One man of our company fainted and two or three fell out before it was over; but most of the men agreed that it was on the whole an easier job than that of the day before.' (Army Life) |

One of the managers of the Relief Association at Philadelphia said to me: "We have a good many regiments through here-thirteen this week, and on an average two regiments a day, now-a-days-and I think I have never seen a regiment of a thousand such universally well-behaved, orderly and gentlemanly men."

Carey, of the 13th Mass., which fine regiment, once of 1100 men, has now 700 in hospital, sick and wounded, and is reduced by losses (in battle mainly) to 191 effective men; by Lieut. "Willie" Root, of the 22d Conn., which was in camp close by us yesterday, but to-day has struck tents and moved away to Chain Bridge; and by others, whose brown and hearty faces it was pleasant to see.'
