In the latter part of October, the surveys of the battlefields being completed, and the men provided with new and well-fitting uniforms, infantry drills were resumed. An order was issued requiring the company to be formed without arms, the next day, in the Alameda, for squad drill. Immediately thereafter, one of my most trusted sergeants informed me that this order caused great dissatisfaction in the company. He said the men felt they would be degraded if now turned back to the beginning--at squad drill without arms--thus placing them in the position of raw recruits, whilst the rest of the army were being exercised at brigade and division drill, "evolutions of the line," with all attendant "pomp and circumstance". The sergeant warned me that the state of feeling in the company would, in his opinion, lead to serious trouble if the order was carried into effect. I thanked him for the information. When the men were formed on the drill ground next day, I told them I was aware of their opposition to the order; but, that I was under the impression I commanded that company, and if there was a man amongst them who felt disposed to dispute my legal authority he was requested to step to the front. No one moved. I then directed the artificers and privates to go to their quarters, and inform the sergeant of the guard they had my permission to be absent until evening parade. Turning to the non-commissioned officers, I stated that, in my judgment, there was no occasion for them to feel degraded if drilled by their own officers at squad drill without arms. I drilled the sergeants, McClellan the corporals. Whilst the non-commissioned officers were being thus drilled, the men were allowed daily liberty from quarters. Later, the non-commissioned officers drilled the men in squads under the supervision of the officers. Instruction and practice in the infantry "School of the Company" was then resumed; and, after a time, each non-commissioned officer was required, in turn, to take his place by my side and drill the company. On those occasions, the men were warned that no inattention or remissness on their part would be tolerated; no matter how lenient with them I might choose to be when commanding in person. It is safe to say that within six weeks from the time squad drills without arms were commenced in the engineer company, in the City of Mexico, that company as Infantry, was better drilled than any other in the army. In that respect, and in discipline, they were pattern soldiers. Regular instruction in the "School of the Engineer Soldier" was then resumed. From raw recruits, on the Rio Grande, disturbed by the epithet, "pick and shovel brigade" applied to them, at that time, by the soldiers of the line, the engineer company had become veterans of more than half a dozen important battles; had always been in the front of the fighting; and had often been called upon to direct large working parties of soldiers, detailed to use the "pick and shovel".
