General Worth, with his division somewhat reinforced, was given the task of gaining possession of the Saltillo road, and of carrying the detached works outside the city, in that quarter.

He started on his march early in the afternoon of the 20th.

The divisions under Generals Butler and Twiggs were drawn up to threaten the east and north sides of the city and the works on those fronts, in support of the movement under General Worth.

Worth's was regarded as the main attack on Monterey, and all other operations were in support of it.

His march this day was uninterrupted; but the enemy was seen to reinforce heavily about the Bishop's Palace and the other outside fortifications on their left.
