Orlando Poe came about the same time, for all this was occurring in the last ten days of April. He was a lieutenant of topographical engineers, and was stationed with General (then Captain) Meade at Detroit, doing duty upon the coast survey of the lakes. He was in person the model for a young athlete, tall, dark, and strong, with frank, open countenance, looking fit to repeat his ancestor Adam Poe's adventurous conflicts with the Indians as told in the frontier traditions of Ohio. He too was eager for service; but the same rule was applied to him, and the argument that the engineers would be especially necessary to the army organization kept him for a time from insisting upon taking volunteer service, as McCook had done. He was indefatigable in his labors, assisting the governor in organizing the regiments, smoothing the difficulties constantly arising from lack of familiarity with the details of the administrative service of the army, and giving wise advice to the volunteer officers who made his acquaintance. I asked him, one day, in my pursuit of practical ideas from all who I thought could help me, what he would advise as the most useful means of becoming familiar with my duties. Study the Army Regulations, said he, as if it were your Bible! There was a world of wisdom in this: much more than I appreciated at the time, though it set me earnestly to work in a right direction. An officer in a responsible command, who had already a fair knowledge of tactics, might trust his common sense for guidance in an action on the field; but the administrative duties of the army as a machine must be thoroughly learned, if he would hope to make the management of its complicated organization an easy thing to him. Major Sidney Burbank came to take McCook's place as mustering officer: a grave, earnest man, of more age and more varied experience than the men I have named. Captain John Pope also visited the governor for consultation, and possibly others came also, though I saw them only in passing, and did not then get far in making their acquaintance.
