Fully-manned in the summer of 1941, and commanded by the truly formidable BGen. Mateo M. Capinpin, the 1st Regular Division of the Philippine Army completely gave its manpower in late August to help fill in the beginning ranks of the  Army's ten Reserve Divisions, which were just being mobilized and manned. From September through late November, the 1st Regular Division was, for all practical purposes, de-activated. But its few personnel who remained—and the American and Philippine area commanders who oversaw the emergency reorganizations—were ready to implement careful plans to reassemble enough personnel to re-activate the 1st Division quickly, and then begin filling back in its ranks. When Japanese hostilities broke out on 8 Dec 1941, the 1st Regular Division was only at cadre strength (just its commissioned and senior non-commissioned officers). Within ten days , 18 Dec 1941, it was re-activated and inducted back into the force tabulations of BGen. George M. Parker's South Luzon Force. Its new commanding general, the tough and brilliant West Pointer, BGen. Fidel V. Segundo (PA), set his hand to the task of continuing to bring the Division's units back up to as full a strength possible, all the while fighting a difficult staged retreat from South Luzon into the Bataan peninsula.
