ad separated from the main body of our Army; bands of
guerrilleros and robbers infested the roads, harassed our trains, and
whenever it was in their power cut off our supplies.

The Mexicans having thus shown themselves to be wholly incapable of
appreciating our forbearance and liberality, it was deemed proper to
change the manner of conducting the war, by making them feel its
pressure according to the usages observed under similar circumstances by
all other civilized nations.

Accordingly, as early as the 22d of September, 1846, instructions were
given by the Secretary of War to Major-General Taylor to "draw supplies"
for our Army "from the enemy without paying for them, and to require
contributions for its support, if in that way he was satisfied he could
get abundant supplies for his forces." In directing the execution of
these instructions much was necessarily left to the discretion of the
commanding officer, who was best acquainted with the circumstances by
which he was surrounded, the wants of the Army, and the practicability
of enforcing the measure. General Taylor, on the 26th of October, 1846,
replied from Monterey that "it would have been impossible hitherto, and
is so now, to sustain the Army to any extent by forced contributions of
money or supplies." For the reasons assigned by him, he did not adopt
the policy of his instructions, but declared his readiness to do so
"should the Army in its future operations reach a portion of the country
which may be made to supply the troops with advantage." He continued to
pay for the articles of supply which were drawn from the enemy's
country.

Similar instructions were issued to Major-General Scott on the 3d of
April, 1847, who replied from Jalapa on the 20th of May, 1847, that if
it be expected "that the Army is to support itself by forced
contributions levied upon the country we may ruin and exasperate the
inhabitants and starve ourselves." The same discretion was given to him
that had been to General Taylor in this respect. General Scott, for the
reasons assigned by him, also continued to pay for the articles of
supply for the Army which were drawn from the enemy.

After the Army had reached the heart of the most wealthy portion of
Mexico it was supposed that the obstacles which had before that time
prevented it would not be such as to render impracticable the levy of
forced contributions for its support, and on the 1st of September and
again on the 6th of Octob
