Activation
The 79th Division "Liberty" Division, also known as the "Lorraine" Division, was a National Army division established 5 August 1917 by the War Department to be formed at Camp Meade, Maryland. The division was commanded by Maj. Gen. Joseph E. Kuhn. Draftees were from Pennsylvania and Maryland. Movement overseas commenced on 6 July 1918 and was completed by 3 August 1918. The 157th Infantry Brigade was commanded by Brig. Gen. William Jones Nicholson. [1]
The Brigade consisted of:
-
Headquarters and Headquarters Company -
313th Infantry Regiment -
314th Infantry Regiment - 311th Machine Gun Battalion
Shrouded in secrecy, the brigade left from Hoboken, New Jersey in July 1918 on the SS Leviathan, a speedy ex-German liner that arrived at Brest, France the morning of 15 July 1918. They trained for two months at Champ Little behind the French lines. On 26 September 1918 they "went over the top" in the Meuse-Argonne offensive. In a period of heartbreaking losses, the men struggled through nine kilometers of barbed wire and pot-marked earth. They destroyed German defenses that were said to be impregnable. [2] That night they were on the outskirts of Montfaucon, headquarters of the enemy command. The 313th fought until the end, 11 November 1918. Gen. John J. Pershing commended the men of the 79th Division, and especially the 313th Infantry Regiment whose forces penetrated deeper into enemy territory than any other outfit.
Organization from 1963 to 1995
The 157th Infantry Brigade (Mechanized) was reactivated on 3 January 1963 in Upper Darby, Pennsylvania using assets from the inactivating 79th Infantry Division. It moved to Horsham on 31 January 1968, where it remained until its inactivation on 1 September 1995 during the post-Cold War drawdown. In 1966 this Brigade consisted of 3 Infantry Battalions: the 1–313th IN co-located Indiantown Gap Military Reservation (IGMR), since redesignated Fort Indiantown Gap (FIG), Annville, PA; and at Lock Haven, PA; the 1–314th IN (Mechanized) co-located at Bristol and Warrington, PA; the 1–315th IN located at 5200 Wissahickon Ave, Philadelphia, PA. It had 2 Armor Battalions at that time: namely, the 4–77th AR (location uncertain) and the 6–68th AR co-located at Bethlehem, PA and IGMR, PA. After the Arab-Israeli War of 1967, the 4–77th was disbanded, its armored vehicles sent to Israel to replace Israeli losses, and its personnel merged into the 6–68th AR. That same year, the Brigade's 1–314th IN (Mechanized) lost its armored vehicles- primarily M578s, M113s, M59s and M577s all of which were also sent to Israel to replace their war losses. It was not until the summer of 1971 that the 1–314th IN was re-designated a Mechanized unit. By the summer of 1973 the 1–313th IN was disbanded with its personnel and company units redesignated as part of the 1–314th IN.

- Headquarters and Headquarters Company – Horsham, Pennsylvania
