Otis's brigade on the left consisted in the order given of the Kansas, the Third Artillery (infantry), and the Montana regiment; in the center was the divisional artillery under Major Young and then troops of the Fourth United States Cavalry, and on the right was Hale's command, containing the Tenth Pennsylvania, South Dakota and Nebraska regiments. The Nebraskans were on the extreme right, while the Kansans formed the pivotal regiment. The artillery designated to take part in the forward movement were two B. and L. rifles, under command of Lieutenant Critchlow; two B.L. rifles of the Sixth United States Artillery, under Lieutenant Fleming, and an automatic gun under command of Ensign Davis of the navy. On the evening of the 24th Lieutenant Fleming's guns were removed from the old intrenchment in front of Fort MacArthur, and were replaced by two B. and L. rifles under Lieutenant Gibbs of Battery A, who had formerly been stationed in front of the Colorado line at Sampaloe. Major Grant at this period was no longer in immediate command of Battery B, as he had been detailed as commander of the river gunboats on February 17th. During the period of waiting the Government mules had arrived and the rifles under Lieutenants Critchlow and Fleming were now equipped for the journey into the jungle. Few artillery exploits can compare in dash and daring with that performed by Lieutenant Naylor out on the right of the line early in the morning of the 25th. Many brave and reckless deeds with guns at close range were done by artillery forces on other occasions in the Filipino campaign, but it is hardly probable that any field pieces have been rushed so far beyond infantry support as they were on this day before the enemy at San Francisco del Monte. Lieutenant Naylor's position lay in a sunken road at a point where the lines of the Tenth Pennsylvania and South Dakota regiments joined. For a distance of about 800 yards the road, which had been constructed by the Spanish, extended toward the Tagalan earthworks. At the point the road abruptly ends, and there is a plat of hard ground. Fifty yards farther on a rude barricade had been erected as a shelter for the native outposts, and a hundred yards in advance of this the enemy's strong line of earthworks widened out across the top of a gently rising eminence. This position had been accurately located several days previously by a reconnoitering party.
