Tracking the Regiment: On September 29 and 30, 1918, Allied forces including the men of Seventh Regiment executed their attack at The Hindenburg Line. With tanks exploding around them, the men of Companies B and C encountered the enemy within 25 yards of launching their attack at great loss of life. Company D followed and captured 60 prisoners within the first ten minutes of battle. Trench after trench, the men pressed forward at great expense: more than half of the Regiment were either killed or injured on the first day of battle and only 5 officers remained, making it the largest daily loss in any American Regiment during WWI.
Included among the casualties was Captain Fancher Nicoll (Company L), a 39-year-old lawyer and father of two who joined the Regiment in 1900 and was part of two old New York families who dated back to the Revolutionary War. It was reported in The New York Times that even as Captain Nicoll himself was dying, he reached out his hand to comfort the wounded beside him.
Sgt. John C. Latham, Sgt. Alan Eggers and Cpl. Thomas O'Shea of Machine Gun Company, 107th, became separated from the regiment during the Battle of the Hindenburg Line. They took cover where they could, which ended up being in a shell hole within enemy lines. Hearing a cry for help, they realized it was coming from a disabled American tank nearby. All three left the safety of their shelter and headed toward the tank, despite the heavy machine-gun fire. The 23-year-old O'Shea was hit along the way and died. Latham and Eggers made it to the tank, where they were able to rescue a wounded officer and help two other soldiers find cover in a nearby trench. They headed back to the tank, despite the heavy fire, and wrestled the machine gun off, taking it back to the trench with the wounded men. They were able to use that gun to fend off German attackers for the rest of the day. When darkness fell, all of the surviving men were able to make it back to Allied lines. For their bravery and quick thinking, Latham, Eggers and O'Shea all earned the Congressional Medal of Honor.
By the end of the second day of battle, the Regiment sustained 335 casualties and 884 wounded men, having captured nearly 2,000 enemy troops. By October 1, the last major German defense line was penetrated, and the Allies continued to advance and attack the fleeing German troops in the open country beyond.
