On that day, near Montélimar, France, he provided covering fire for a combat medic who was evacuating wounded men to safety.
Gregg was subsequently promoted to second lieutenant and, on April 17, 1945, was presented with the Medal of Honor by Lt. Gen. Alexander M. Patch Jr., Commanding General of the U.S. 7th Army.
[2] Gregg returned to Bayonne in 1945 and was greeted with a parade attended by 50,000 people, during which he met his future wife, Irene Zawalick, whom he married in 1947.
He went to work for the Hudson's County Sheriff's Department and retired as chief of court officers in 1996, after fifty one years of service.
Realizing the seriousness of the situation, Second Lieutenant Gregg took one of the light .30-caliber machineguns, and firing from the hip, started boldly up the hill with the medical aid man following him.
The following morning, just prior to daybreak, the Germans launched a strong attack, supported by tanks, in an attempt to drive Company L from the hill.
As these tanks moved along the valley and their foot troops advanced up the hill, Second Lieutenant Gregg immediately ordered his mortars into action.
