By General TYLER:

Question. How, when, and where did the enemy's cavalry destroy our communication?

By cutting the railroad, about the 28th of August, between McMinnville and Tullahoma.

Question. Did that cavalry pass over by Altamont?

I was informed that they had passed near Altamont.

Question. How, when, and where?

I was informed they had passed over the mountains by some road not generally traveled. I am not acquainted with the roads in that neighborhood, other train those leading into Altamont, and I cannot say by what exact route they crossed. From what I saw of the range I should judge the cavalry could cross in a great many places.

Question. At what point was the Tullahoma and McMinnville Railroad cut?

I cannot be positive. I was informed, if I am not mistaken, that it was between McMinnville and Manchester.

Question. What id the distance between McMinnville and Manchester?

I never traveled the route but once and did not pay particular attention to the distance, but I should think it would be from 15 to 20 miles.

Question. Do you know anything personally of the country between Tullahoma and McMinnville, and also do you know personally of any route by which those cavalry could come over and cut the communications?

I only know from traveling the road from Tullahoma to Manchester three times and from McMinnville to Manchester once. As to crossing the mountains other than by some three roads on the west, and one or two on the east, entering at Altamont, as before stated, I have no positive information, and relied upon the representations of the people of the country.

Question. Do you know by which of these three roads the cavalry came over and cut those communication?

I do not. My impression is that they did not come up either of these three roads-roads used for wagons, more or less-and was informed, as before stated, that the cavalry used a less public route, avoiding Altamont.

Question. What did you do with the letter written by the son of the clerk of Grundy County?

I appended it to the report of the expedition made to General Wood.

Question. You stated that there were some 200 head of cattle in the coves about Altamont; were these cattle collected for the use of our army?

Not to my knowledge.

Question. Was the army then in a condition to require fresh meat?

I believe we were at that time on full rations, though meat might have been used to great advantage. We were very shortly thereafter limited in rations.

Question. At what time were you at Altamont and what was the condition of the crops while you were there?

I was at Altamont about the 23rd of August. In the immediate vicinity of Altamont there were no crops worth mentioning, it being an exceedingly sterile country.

Question. Was there any green or dry forage there?

A few farmers had a very little, but not enough to pay for gathering up. In the coves at the foot of the mountain the farmers had a very fair yield of corn, but very little dry corn or old forage, many farmers having none.
