Battle of the Bulge in the context of "Operation Grenade"

Matthew Bunker Ridgway (3 March 1895 – 26 July 1993) was a senior officer in the United States Army, who served as Supreme Allied Commander Europe (1952–1953) and the 19th Chief of Staff of the United States Army (1953–1955). Although he saw no combat service in World War I, he was intensively involved in World War II, where he was the first Commanding General (CG) of the 82nd Airborne Division, leading it in action in Sicily, Italy and Normandy, before taking command of the newly formed XVIII Airborne Corps in August 1944. He held the latter post until the end of the war in mid-1945, commanding the corps in the Battle of the Bulge, Operation Varsity and the Western Allied invasion of Germany.

Ridgway held several major commands after World War II and is most well-known for resurrecting the United Nations (UN) war effort during the Korean War. Several historians have credited Ridgway for turning the war around in favor of the UN side. He also persuaded President Dwight D. Eisenhower to refrain from direct military intervention in the First Indochina War to support French colonial forces, thereby essentially delaying the United States' Vietnam War by over a decade. He received the Presidential Medal of Freedom on 12 May 1986. Ridgway died in 1993 at the age of 98.

The Malmedy massacre was a German war crime committed by soldiers of the Waffen-SS on 17 December 1944 at the Baugnez crossroads near the city of Malmedy, Belgium, during the Battle of the Bulge (16 December 1944 – 25 January 1945). Soldiers of Kampfgruppe Peiper summarily killed eighty-four U.S. Army prisoners of war (POWs) who had surrendered after a brief battle. The Waffen-SS soldiers had grouped the U.S. POWs in a farmer's field, where they used machine guns to shoot and kill the grouped POWs; many of the prisoners of war who survived the gunfire of the massacre were executed with a gunshot to the head.

Besides the summary execution of the eighty-four U.S. POWs at the farmer's field, the term "Malmedy massacre" also includes other Waffen-SS massacres of civilians and POWs in Belgian villages and towns in the time after their first massacre of U.S. POWs at Malmedy; these Waffen-SS war crimes were the subjects of the Malmedy massacre trial (May–July 1946), which was a part of the Dachau trials (1945–1947).

The Western Allied invasion of Germany was coordinated by the Western Allies during the final months of hostilities in the European theatre of World War II. In preparation for the Allied invasion of Germany east of the Rhine, a series of offensive operations were designed to seize and capture its east and west banks: Operation Veritable and Operation Grenade in February 1945, and Operation Lumberjack and Operation Undertone in March 1945; these are considered separate from the main invasion operation. The Allied invasion of Germany east of the Rhine started with the Western Allies crossing the river on 22 March 1945 before fanning out and overrunning all of western Germany from the Baltic in the north to the Alpine passes in the south, where they linked up with troops of the U.S. Fifth Army in Italy. Combined with the capture of Berchtesgaden, any hope of Nazi leadership continuing to wage war from a so-called "national redoubt" or escape through the Alps was crushed, shortly followed by unconditional German surrender on 8 May 1945. This is known as the Central Europe Campaign in United States military histories.

By early 1945, events favored the Allied forces in Europe. On the Western Front, the Allies had been fighting in Germany with campaigns against the Siegfried Line since the Battle of Aachen, the Battle of Metz and the Battle of Hürtgen Forest in late 1944 and by January 1945, had pushed the Germans back to their starting points during the Battle of the Bulge. The failure of this offensive exhausted Germany's strategic reserve, leaving it ill-prepared to resist the final Allied campaigns in Europe. Additional losses in the Rhineland further weakened the German Army, leaving shattered remnants of units to defend the east bank of the Rhine. On 7 March, the Allies seized the intact bridge across the Rhine at Remagen, and established a large bridgehead on the river's east bank. During Operation Lumberjack, Operation Plunder and Operation Undertone, German casualties during February–March 1945 are estimated at 400,000 men, including 280,000 men captured as prisoners of war.

A salient, also known as a bulge, is a battlefield feature that projects into enemy territory. The salient is surrounded by the enemy on multiple sides, making the troops occupying the salient vulnerable. The opponent's front line that borders a salient is referred to as a re-entrant – that is, an angle pointing inwards. A deep salient is vulnerable to being "pinched off" through the base, and this will result in a pocket in which the forces in the salient become isolated and without a supply line. On the other hand, a breakout of the forces within the salient through its tip can threaten the rear areas of the opposing forces outside it, leaving them open to an attack from behind.

William Kelly Harrison Jr. (September 7, 1895 – May 25, 1987) was a highly decorated officer in the United States Army with the rank of Lieutenant General. A graduate of the United States Military Academy, he rose through the ranks to brigadier general during World War II and distinguished himself in combat several times, while serving as the assistant division commander of the 30th Infantry Division during the Normandy Campaign and the Battle of the Bulge. Harrison was decorated with the Distinguished Service Cross, the second highest decoration of the United States military for bravery in combat, for his actions during Operation Cobra.

Following the War, Harrison remained in the Army and after several stateside assignments, he was ordered to the Far East, where he served as head of the United Nations Command armistice delegation in the Korean War. He participated in the truce talks, which concluded with the signing of the Korean Armistice Agreement on July 27, 1953. Harrison completed his career as the commanding general of U.S. Caribbean Command in early 1957.

Operation Northwind (German: Unternehmen Nordwind) was the last major German offensive of World War II on the Western Front. Northwind was launched to support the German Ardennes offensive campaign in the Battle of the Bulge, which by late December 1944 had decisively turned against the German forces. It began on 31 December 1944 in Rhineland-Palatinate, Alsace and Lorraine in southwestern Germany and northeastern France, and ended on 25 January 1945. The German offensive was an operational failure, with its main objectives not achieved.
