The artillerymen fired a last ceremonial round at 1100 to mark the occasion. The remaining soldiers and most of the heavy equipment traveled to the city by vehicle, handing over the firebase to soldiers from the South Vietnamese 3d ID as they departed. #ArmyHistory

By the summer of 1972 the withdrawal from Vietnam was in its final phase, and TF GIMLET was the only U.S. ground combat unit still in the field. On 10 AUG 1972, 4 UH-1 “Huey” helicopters extracted most of the soldiers from Hill 260 and flew them to the airbase in Da Nang.

The task force operated from Hill 260 on the outskirts of Da Nang, the largest city and the principal port in the northern half of South Vietnam. Its mission was to defend the city and its large airbase from enemy units operating in the nearby hills and valleys.

Known as the “Gimlets,” a nickname the regiment acquired in the 1920s for its sporting prowess while posted in Hawaii, the men of the 3d BTLN had teamed with the gunners from Battery B, 3d BTLN, 82d Art., as Task Force GIMLET since JUN 1972. #Americal #ArmyAviation.

11 AUGUST 1972 – LAST GROUND UNITS DEPART VIETNAM . The last U.S. maneuver battalion to leave South Vietnam was the 3d Battalion, 21st Infantry, formerly a part of the 196th Infantry Brigade, 23d “Americal” ID. #USArmy #TRADOC #VietnamWar #VietnamWarHistory

@USArmy @TRADOC Realizing that his men were exhausted and low on ammunition, Sturgis ordered a retreat to Springfield. But the victorious Confederates were too disorganized and ill-equipped to pursue and exploit their tactical success.

@USArmy @TRADOC The rebels counterattacked but failed to break through the U.S. lines in three attempts that day. After being wounded twice during the battle, Lyon was killed while trying to rally his troops. In the meantime, rebel forces routed Sigel’s column, south of Skegg’s Branch.

@USArmy @TRADOC Initially caught by surprise, the rebel cavalry received the first blow and withdrew from a ridge later named Bloody Hill, but other Confederate forces soon rushed to the scene and stabilized their positions.

His force advanced in two columns, one under his direct command and the other under COL Franz Sigel, to attack the Confederates encamped on Wilson’s Creek, about 12 miles southwest of Springfield. @USArmy @TRADOC

On 9 AUG, the U.S. and rebel commanders formulated their respective plans of attack. Lyon moved first, at about 0500 on 10 AUG, even though he was outnumbered by his opponents. #USArmy #TRADOC #CivilWar #CivilWarHistory #ArmyHistory #MilitaryHistory

A rebel force consisting of the pro-secessionist Missouri State Guard commanded by MG Sterling Price and a Confederate army brigade commanded by BG Ben McCulloch sought to destroy Lyon's force and install a pro-Confederate government.

10 AUGUST 1861 – BATTLE OF WILSON'S CREEK . After defeating pro-Southern militia in a series of small engagements, BG Nathaniel Lyon’s U.S. Army of the West engaged secessionist forces at Wilson’s Creek in the first major battle in the Civil War’s Trans-Mississippi Theater.

@TRADOC @USArmy By 5 OCT, the offensive broke through the Hindenburg Line, and Allied forces advanced through open country to the Oise-Somme Canal on 19 OCT. The U.S. II Corps was relieved on 21 OCT after 26 days in the line and suffered 11,500 casualties.

@TRADOC @USArmy As part of the British Fourth Army, the American II Army Corps, with the 27th and 30th DIV, attacked the Germans along the line of the Cambrai-St. Quentin Canal and captured heavily fortified Bony and Bellicourt on 29 SEP. #ArmyHistory #MilitaryHistory #PrairieDivision

@TRADOC Field Marshal Erich Ludendorff characterized 8 AUG as the "Black Day of the German Army." The Germans were forced to retreat to the line they had originally established in 1915, where they reorganized strong defenses-in-depth. #BlueRidgeDivision #BattleOfTheSomme @USArmy

Approximately 600 tanks led the assault, which commenced during a thick fog. The attack achieved complete surprise as Allied troops quickly overran the German positions and took 16,000 prisoners. #USArmy #TRADOC #WWI #WW1 #WW1History #OldHickoryDivision @TRADOC

The British Fourth Army, with the U.S. 33d and 80th DIV attached, attacked the northwestern edge of the salient. To achieve maximum surprise, and contrary to standard procedure, no rolling artillery barrage preceded the advancing infantry to not forewarn the enemy.

8 AUGUST - 11 NOVEMBER 1918 – ANGLO-AMERICAN SOMME OFFENSIVE. On 8 AUG the British, bolstered by fresh units from the American Expeditionary Forces (AEF), began limited operations with the objective of flattening the Amiens salient as it sought to reverse German gains.
