Leaving Worth and his gallant men thus in full possession of the western gate of Monterey, we will now trace Taylor's operations at the opposite end of the town. Sunday afternoon, observing the Mexican reinforcements hastening to the summit of Independence Hill and fearing Worth might be overpowered, he displayed most of his troops before the city until dark as a menace. During the night his 10-inch mortar and two 24-pound howitzers were planted about seven eighths of a mile from the citadel, near the forward edge of a depression which screened them from the enemy, and at seven o'clock the next morning these pieces fired for twenty minutes, doubtless encouraging rather than alarming the enemy by their ineffective work.[12.10] At the same time, to divert attention from Worth, as a note from that officer had suggested, all the available infantry were drawn out before the citadel as if to assault it. The First Division (regulars) stood at the left of this line; Quitman's brigade--the Tennesseeans under Campbell and the Mississippi riflemen under Davis--came next it, and Hamer with the Ohio regiment occupied the extreme right. Meanwhile the work of reconnoitring continued. Believing that he would meet with no serious resistance at Monterey, Taylor had apparently felt little or no anxiety to ascertain how the town had been fortified; but now he may have realized that such information was desirable.[12.10] In a general sense we are already aware what defences had been prepared in this quarter--particularly the barricaded streets and the stone houses turned into forts; but the situation must now be investigated more closely. West of the grand plaza and toward the northern edge of the city there was a large spring. The outlet of this flowed toward the east, widened into a pond, then contracted into a stream, passed under Purísima bridge--a heavy structure of stone by which the Marín road entered the city proper--veered a little toward the right, and finally left the town at its northeastern corner. On the inner side of this watercourse below Purísima bridge there were two simple redans capable of holding fifty or seventy men each; and some distance farther down, on the top of a rather steep slope, stood a strong earthwork named El Rincón del Diablo (The Devil's Corner), commonly known by the Americans as El Diablo, which had two or three guns, and could accommodate a garrison of one hundred and fifty or two hundred.[12.10]
