Company 'A', corps of engineers, U.S.A., 1846-'48, in the Mexican war — Part 35

I communicated my wishes to Major Loring; and asked him if he felt authorized to support the engineer company, with the Rifle Regiment, in a close reconnaissance of the building I pointed out. He laughingly replied: "I have been directed by General Smith to follow you and your company--of course I will go with you".

We had not proceeded more than two hundred yards towards the building when we were overtaken by Lieutenant Van Dorn, Aide to General Smith, who brought an order requiring the Rifle Regiment and the engineer company to return to the head of the column on the road. I told Van Dorn the purpose I had in view, asked him to explain the matter to General Smith, and expressed my conviction that he would approve the movement, when he knew its object. Van Dorn replied: "General Smith was very peremptory. I am directed to see that you and Major Loring, with your respective commands, return at once". On our way back, Van Dorn said that General Pillow had reached the front and taken control; and his belief was that General Pillow had ordered General Smith to recall the engineer company and the Rifle Regiment. A short time thereafter we moved from San Angel to Coyoacan, where the head of the column again halted; and was soon joined by General Scott.

There is good reason to believe that observations, which could easily have been made from the roof of the high building above referred to, would have resulted in obtaining such information in regard to the Mexican position at the Convent of Churubusco and at the _tête-de-pont_, as would have enabled General Scott to complete the rout of the Mexican Army without incurring the additional loss of nearly one thousand men in killed and wounded.

AT CHURUBUSCO. The following quotations are taken from my official report:

"Between 12 and 1 o'clock, P. M., [August 20, 1847] I received orders to move, from the village of [Coyoacan] immediately after the rifle regiment, on a road intersecting the road from San Antonio to Mexico, in order to cut off the enemy already retreating from San Antonio.
