Of course the first essential thing to do was to break the backbone of the insurgent army, and scatter it, and the next thing to do was to capture Aguinaldo, the head and front of the whole business, the incarnation of the aspirations of the Filipino people. The operations to this end commenced in October, and involved three movements of three separate forces: (1) A column under General Lawton, proceeding up the Rio Grande and along the northeastern borders of the plain, and bending around westward along its northern boundary toward the gulf of Lingayen, garrisoning the towns en route, and occupying the mountain passes on the northeast which give exit over the divide into the great valleys beyond. (2) An expedition under General Wheaton, some 2500 in all, proceeding by transports to the gulf of Lingayen, the chief port of which, Dagupan, was the northern terminus of the railroad; the objective being to land on the shore of that gulf at the northwest corner of the plain, occupy the great coast road which runs from that point to the northern extremity of the island, and also to proceed eastward and effect a junction with the Lawton column. (3) A third column under General MacArthur, proceeding up the railroad to the capture of Tarlac, the third insurgent capital, and thence still up the railroad to its end at Dagupan, driving the enemy's forces before it toward the line held by the first two columns. On October 12th, General Lawton moved up the Rio Grande from a place called Aryat, a few miles up stream from where the railroad crosses the river at Calumpit, driving the insurgents before him to the northward and westward. His command was made up mainly from the 3d Cavalry and the 22d Infantry, together with several hundred scouts, American and Maccabebee. On the 20th San Isidro was again captured. That was the place Lawton had evacuated in May previous. Arriving in the Islands with Colonel E. E. Hardin's regiment, the 29th U. S. Volunteer Infantry, on November 3, 1899, the writer was immediately detailed to the Maccabebee scouts, to take the place of Lieutenant Boutelle, of the regular artillery, a young West Pointer from Oregon, who had been killed a day or two previous, and reported to Major C. G. Starr, General Lawton's Adjutant-General in the field (whom he had known at Santiago de Cuba the previous year) at San Isidro on or about November 8th. Major Starr said: "We took this town last spring," stating how much our loss had been in so doing, "but, partly as a result of the Schurman Commission parleying with the insurgents General Otis had us fall back. We have just had to take it again." General Lawton garrisoned San Isidro this time once for all, and pressed on north, capturing the successive towns en route. Meantime, General Young's cavalry, and the Maccabebee scouts under Major Batson, a lieutenant of the regular army, and a medal-of-honor graduate of the Santiago campaign, were operating to the west of the general line of advance,
