German offensives in the spring of 1918 had penetrated deep into the allied lines, and created salients near Amiens and Hazebrouck.

[2] The assault began with the 105th on the left side of the advance (abreast with the 106th Infantry), and fighting continued for a few days until the regiment was relieved by the British 41st Division.

On 27 September 1918, 1LT Turner was leading his men in an attack, under terrific artillery and machine-gun fire, after they had become separated from the rest of the company in the darkness.

[3] While Germany and Fascist Italy were in the process of conquering most of Europe in 1939 and 1940, and the Empire of Japan was grabbing territory in the Pacific and China, the United States felt unprepared in the event war was necessary to combat the Axis Powers and began mobilizing its army in response.

As the landing craft approached the beach, they began to receive small-arms and machine-gun fire from the island's defenders.

Equipment and weapons were lost or water-soaked, but only three men were killed approaching the beach, mainly because the defenders chose to make their final stand farther inland along the tank barriers.

On 19 June, 1-105 advanced on Nafutan Point under the command of LTC William J. O'Brien but became bogged down, and despite armored support and flanking maneuvers, the Japanese position was too strong.

[6] Meanwhile, on 23 June 1944, the units of the 27th Division advanced up what the soldiers called "Death Valley" and "Purple Heart Ridge" toward Mount Tapotchau.

LTC O'Brien led the defense in the 1-105 area, with a pistol in each hand and even manning a nearby .50 Caliber machine-gun until he was killed.

When American forces retook the position, they found the pistol, then empty, and eight dead Japanese soldiers around Baker's body.

Salomon was able to kill the enemy that entered the hospital tent and ordered the wounded to be evacuated, while he stayed to cover their withdrawal.

The fighting on 7 July decimated the regiment, and the memory of that night would define the character of the survivors, and set forth a courageous tradition for the future.

[7] The regiment had slowly begun refilling its ranks with replacement officers and men, but were definitely still understrength and weary by the time they departed for Okinawa on 25 March 1945.

Here in southern Okinawa, the 105th was mired in mud, torrential rainfall, and static warfare reminiscent of the First World War.

[9]" After suffering heavy casualties at Okinawa, the beleaguered men of the 105th arrived in Japan on 12 September 1945 to serve a garrison role, and the regiment was inactivated on 12 December 1945 when it returned home to the United States.
