Cyril J. O'Brien, Liberation: Marines in the Recapture of Guam
“ The regiment received intense mortar and artillery fire coming in and on the beaches, and faced the toughest terrain—steep cliffs whose approaches were laced with interlocking bands of Japanese machine gun fire. The cliffs were defended by foes who knew and used their weapons well. The Japanese, that close, would roll grenades right down the escarpment onto the Marines. Snipers could find protection and cover in the countless folds and ridges of the irregular terrain, and the ridgetops were arrayed like the breastworks of some nightmarish castle. ”
