Reading edition
On 13 November the 1st and 2d Battalions took up the fight, with machine guns from the vicinity of OP Hill firing in support. The 1st and 2d Battalions advanced 600 and 400 yards, respectively. By 14 November it appeared to General Irving that the 21st Infantry had eliminated nearly all resistance on Breakneck Ridge. The regiment controlled the ridge proper, but several adjacent spurs, notably Corkscrew Ridge, were still controlled by the 57th Infantry. On 15 November the 1st Battalion, the most advanced unit, was about 1,500 yards north of Limon. On 16 November the 128th Infantry of the 32d Division relieved the 21st Infantry. The battle of Breakneck Ridge had not been an easy one for the 21st Infantry; it had lost 630 men killed, wounded, and missing, together with 135 men from other causes. By actual count it had killed 1,779 Japanese.72
