"At Vera Cruz my men were worked too hard; many of them are suffering yet from disease contracted there. Time, labor and life would have been saved if we had had the proportion of engineer soldiers usual in the armies of civilized nations. At Cerro Gordo, when I could furnish ten men [for details], fifty, at least, were necessary. In the operations in this valley, the same necessity has been felt for a larger number of soldiers of this character. There ought to be more companies of engineer soldiers in this army. Certainly, measures should be taken to complete the number of men allowed in the only company now authorized. I know of none so likely to succeed as sending an officer and non-commissioned officers [to the United States] on this duty". In my official report for the month of November, 1847, it is stated: "The system of instruction now being pursued is the following: From 9 A. M. until 10:45 A. M., recitations and instruction of the whole company, under direction of both officers, in _Manuel du Sapeur_, together with lectures and recitations on field fortifications. From 11 A. M. until 12:30 P. M., [infantry drill]. From 2 P. M. until 4 P. M., recitations in arithmetic and practice in writing. Each officer has a section in arithmetic, and gives a general superintendence to a section in writing. Instruction in writing is given by sergeants". "I have nothing new to offer either in reference to the property, the enlistment of men, or the settlement of the accounts of the late Captain Swift. All, in my opinion, matters of importance; but already referred to, [in previous reports and correspondence], perhaps, too often". "It is just one year since, by the casualties of service, the command of this company devolved upon myself as the senior officer for duty with the engineer troops. During this time the interests of the general engineer service, particularly of the non-commissioned officers and men, have materially suffered for want of an officer of rank at the head of the company. In the French service _two_ captains are assigned to every company of this character, and the companies are all [well] instructed before they take the field. I earnestly recommend that four officers of engineers be assigned to duty with this company. The commander should be an officer of rank; his position permanent. In case the Chief Engineer should order an officer into the field to take command of Company A, engineers, I respectfully request that I may be ordered to the United States as soon as relieved from this duty". On the 1st of February, 1848, I reported that the course of instruction, adopted for the company, "had been continued, with satisfactory progress on the part of non-commissioned officers and men". On the 27th of February, 1848, in a letter to Colonel Totten, Chief Engineer, Washington, D. C., transmitting copies of certain papers, I stated:
