[10] From the period of 10 October until the end of the war on 11 November, the division, minus their artillery occupied and conducted local engagements in the Puvenelle Sector (Lorraine).

[9] The division launched a reconnaissance in force on the Voëvre plain, but the main assault was never conducted as hostilities ended on 11 November 1918 with the signing of the Armistice with Germany.

On 11 November, the line is established from 310.2 to 287.1 in the Bois de Grand-Fontaine, the quarry near 278.7, west of Rembercourt, and the small woods ¼ km south of Mon Plaisir Fme.

[7] As the Regular Army was still seriously understrength, most of the early troops in the division were conscripted as a part of the United States' first peacetime military draft.

[9] The 7th Division was assigned to III Corps of the Fourth United States Army,[9] and transferred to Longview, Washington, in August 1941 to participate in tactical maneuvers.

Following this training, the division moved back to Fort Ord, California, where it was located when the Japanese attack of Pearl Harbor caused the United States to declare war.

The formation proceeded almost immediately to San Jose, California, arriving 11 December 1941 to help protect the west coast and allay civilian fears of invasion.

[12] The division was hampered by its inexperience, lack of winter clothing, and poor weather and terrain conditions, but was eventually able to coordinate an effective attack.

[23] After the campaign, the division moved to Hawaii where it trained in new amphibious assault techniques on the island of Maui, before returning to Schofield Barracks on Oahu for brief leave.

[38] The division was reassigned to XXIV Corps, Tenth United States Army, a newly formed command, and began preparations for the assault on Okinawa.

[42] During the operation, the division was bombarded with tens of thousands of rounds of field artillery fire, encountering Japanese armed with spears as it continued its fight across the island.

[46] Japanese also fought using irregular warfare techniques, relying on hidden cave systems, snipers, and small-unit ambushes to delay the advancing 7th Infantry Division.

[47] After the fight, the division began capturing large numbers of Japanese prisoners for the first time in the war, due to low morale, high casualties, and poor equipment.

[51] It was placed on the extreme left flank of the Tenth Army, taking the Ghinen peninsula, Sashiki, and Hanagusuku, fending off a series of Japanese counterattacks.

[52] Despite heavy Japanese resistance and prolonged bad weather, the division continued its advance until 21 June 1945, when the battle ended, having seen 82 days of combat.

[12] The division was slated to participate in Operation Downfall as a part of XXIV Corps under the First United States Army, but these plans were scrapped after the Japanese surrendered following the use of nuclear weapons on Hiroshima and Nagasaki.

[66] Also fighting with the 7th Infantry Division for much of the war were members of the three successive Kagnew Battalions sent by Emperor Haile Selassie I of Ethiopia as part of the UN forces.

[68] Supported by 230 ships of the US Navy,[69] X Corps began landing at Inchon on 15 September 1950, catching the Korean People's Army (KPA) by surprise.

[78][79] The 32nd Infantry crossed the Han River on 25 September to create a bridgehead,[80][81] and the next day, the division advanced to Osan 30 miles (48 km) south of Seoul[82] and linked up with the 1st Cavalry Division of Eighth United States Army which had broken out from the Pusan perimeter starting on 16 September and then began a general offensive northward against crumbling KPA opposition.

[88] The Chinese People's Volunteer Army (PVA) entered the war on the side of North Korea, making their first attacks in late October.

[87] The landing was delayed due to the presence of mines, and by the time X Corps came ashore, ROK forces moving overland had already occupied the ports.

[108] The division reached full strength and saw action around Chechon, Chungju, and Pyeongchang as part of an effort to push the KPA and PVA forces back above the 38th Parallel and away from Seoul.

[112] The division, now assigned to IX Corps, then assaulted and fought a fierce three-day battle culminating with the recapture of the terrain that had been lost near the Hwachon Reservoir just over the 38th Parallel in North Korea.

[125] Thirteen members of the division received the Medal of Honor for their actions during the Korean War: Charles H. Barker,[126] Raymond Harvey,[127] Einar H. Ingman Jr.,[128] William F. Lyell,[129] Joseph C. Rodriguez,[130] Richard Thomas Shea, Daniel D. Schoonover,[131] Jack G. Hanson,[132] Ralph E. Pomeroy,[133] Edward R. Schowalter Jr.,[134] Benjamin F. Wilson,[135] Don C. Faith Jr.,[136] and Anthony T.

[11] In 1991 the Base Realignment and Closure Commission recommended the closing of Fort Ord due to the escalating cost of living on the central California coastline.

[140] Elements of the division including the 2nd Brigade participated in one final mission in the United States before inactivation; quelling the 1992 Los Angeles riots, as part of Operation Garden Plot.

It would also conduct quarterly status checks with the three brigades to discuss readiness and resource issues affecting those units, ensuring that they were at peak performance should they be needed.

[160] On 26 April 2012, Secretary of the Army John M. McHugh announced the 7th Infantry Division headquarters would be reactivated at Joint Base Lewis-McChord in October 2012.

The mission of the headquarters primarily focuses on making sure soldiers are properly trained and equipped, and that order and discipline is maintained in its subordinate brigades.

[162] In the announcement, McHugh denied that the move was made in response to several high-profile misconduct allegations leveled against soldiers from the base in the Afghanistan War such as the Maywand District murders and the Kandahar massacre.
