Note 165 — Chapter III · The Battle of Bunker Hill

“The Chinese attack by ‘shovel’ proved effective and difficult to combat. They burrowed forward almost continuously, even under direct observation. Every foot of advance provided added opportunity to attack Marine COPs with greater impunity. While this activity possibly provided Marines with target practice in both small arms and mortars, these CCF working parties in a narrow trench 7 to 10-feet deep probably took very few casualties.” Col William R. Watson, Jr. ltr to Hd, HistBr, G-3 Div, HQMC, dtd 18 July 67.
