This river, Pantingan, served as boundary line of the I Corps 9Major Gen. Albert Jones, (AUS) and the II Corps Maj. Gen. George M. Parker, Jr.).   The ravines of the Pantingan River Valley, a few thousand yards southward from this point became the graveyard of a good number of officers and non commissioned officers of the I Corps who were mercilessly massacred by the enemy following the fall of Bataan.
