Freikorps were irregular German and other European military volunteer units, or paramilitary, that existed from the 18th to the early 20th centuries. They effectively fought as mercenary or private armies, regardless of their own nationality. In German-speaking countries, the first so-called Freikorps were formed in the 18th century from native volunteers, enemy renegades, and deserters. These, sometimes exotically equipped, units served as infantry and cavalry ; sometimes in just company strength and sometimes in formations of up to several thousand strong. There were also various mixed formations or legions. The Prussian von Kleist Freikorps included infantry, jäger, dragoons and hussars. The French Volontaires de Saxe combined uhlans and dragoons.
The Kapp Putsch, also known as the Kapp–Lüttwitz Putsch, was an attempted coup against the German national government in Berlin on 13 March 1920. Named after its leaders Wolfgang Kapp and Walther von Lüttwitz, its goal was to undo the German Revolution of 1918–1919, overthrow the Weimar Republic, and establish an autocratic government in its place. It was supported by parts of the Reichswehr, as well as nationalist and monarchist factions.
The Battle of Ligny, in which French troops of the Armée du Nord under the command of Napoleon I defeated part of a Prussian army under Field Marshal Blücher, was fought on 16 June 1815 near Ligny in what is now Belgium. The result was a tactical victory for the French, but the bulk of the Prussian army survived the battle in good order, was reinforced by Prussian troops who had not fought at Ligny, and played a role two days later at the Battle of Waterloo. The Battle of Ligny was the last victory in Napoleon's military career.
The British Free Corps was a unit of the Waffen-SS of Nazi Germany during World War II, made up of British and Dominion prisoners of war who had been recruited by Germany. The unit was originally known as the Legion of St George. Research by British historian Adrian Weale has identified 54 men who belonged to this unit at one time or another, some for only a few days. At no time did it reach more than 27 men in strength.
The Sudetendeutsches Freikorps was a paramilitary Nazi organization founded on 17 September 1938 in Germany on direct order of Adolf Hitler. The organization was composed mainly of ethnic German citizens of Czechoslovakia with pro-Nazi sympathies who were sheltered, trained and equipped by the German army and who were conducting cross border terrorist operations into Czechoslovak territory from 1938 to 1939. They played an important role in Hitler's successful effort to occupy Czechoslovakia and annex the region known as Sudetenland into the Third Reich under Nazi Germany.
The Battle of Carlow took place in Carlow town, Ireland on 25 May 1798 when Carlow rebels rose in support of the 1798 rebellion which had begun the day before in County Kildare. The United Irishmen organisation in Carlow led by a young brogue-maker named Mick Heydon who had taken over the leadership following the arrest of the previous leader, Peter Ivers, who was arrested with several other leading United Irishmen at Oliver Bond's house in March of that year, had assembled on the night of the 24th and set off at dawn to attack the county town. Picking up more volunteers along the way, their numbers swelled to around 1,200 they marched completely unopposed.
Hermann Ehrhardt was a German naval officer in World War I who became an anti-republican and anti-Semitic German nationalist Freikorps leader during the Weimar Republic. As head of the Marine Brigade Ehrhardt, he was among the best-known Freikorps leaders in the immediate postwar years. The Brigade fought against the local soviet republics that arose during the German Revolution of 1918–1919 and later was among the key players in the anti-democratic Kapp Putsch of March 1920. After the Brigade's forced disbanding, Ehrhardt used the remnants of his unit to found the Organisation Consul, a secret group that committed numerous politically motivated assassinations. After it was banned in 1922, Ehrhardt formed other less successful groups such as the Bund Viking. Because of his opposition to Adolf Hitler, Ehrhardt was forced to flee Germany in 1934 and lived apolitically in Austria until his death in 1971.

Gen. John Buford during the Gettysburg Campaign and the three-day Battle of Gettysburg. After the war, Keogh remained in the regular United States Army as commander of I Troop of the 7th Cavalry Regiment under George Armstrong Custer during the Indian Wars, until he was killed along with Custer and all five of the companies directly under Custer's command at the Battle of the Little Bighorn in 1876.
During World War II, the German Wehrmacht committed systematic war crimes, including massacres, mass rape, looting, the exploitation of forced labor, the murder of three million Soviet prisoners of war, and participated in the extermination of Jews. While the Nazi Party's own SS forces was the organization most responsible for the genocidal killing of the Holocaust, the regular armed forces of the Wehrmacht committed many war crimes of their own, particularly on the Eastern Front in the war against the Soviet Union.

The "Irish Brigade" was an attempt by Sir Roger Casement to form an Irish nationalist military unit during World War I among Irishmen who had served in the British Army and had become prisoners of war (POWs) in Germany. Casement sought to send a well-equipped and well-organised Irish unit to Ireland, to fight against Britain, in the aim of achieving independence for Ireland. Such an action was to be concurrent with the ongoing war between Britain and Germany, thereby providing indirect aid to the German cause, without the ex-POWs fighting in the Imperial Germany Army itself.
Friesack Camp or Camp Friesack was a special World War II prisoner of war camp where a group of Irishmen serving in the British Army volunteered for recruitment and selection by Abwehr II and the German Army.

The military career of Adolf Hitler, who was the dictator of Germany from 1933 until 1945, can be divided into two distinct portions of his life. Mainly, the period during World War I when Hitler served as a Gefreiter in the Bavarian Army, and the era of World War II when he served as the Supreme Commander-in-Chief of the Wehrmacht through his position as Führer of Nazi Germany.
Operation Greif was a special operation commanded by Waffen-SS commando Otto Skorzeny during the Battle of the Bulge in World War II. The operation was the brainchild of Adolf Hitler, and its purpose was to capture one or more of the bridges over the Meuse river before they could be destroyed. German soldiers, wearing captured British and U.S. Army uniforms and using captured Allied vehicles, were to cause confusion in the rear of the Allied lines. A lack of vehicles, uniforms and equipment limited the operation and it never achieved its original aim of securing the Meuse bridges. Skorzeny's post-war trial set a precedent clarifying article 4 of the Geneva Convention: as the German soldiers removed the Allied uniforms before engaging in combat, they were not to be considered francs-tireurs.
The Normandy massacres were a series of killings in-which approximately 156 Canadian and two British prisoners of war (POWs) were murdered by soldiers of the 12th SS Panzer Division during the Battle of Normandy in World War II.

The killings ranged in scale from spontaneous murders of individual POWs, to premeditated mass executions. Colonel Kurt Meyer, a commander in the 12th SS Panzer Division, was the only perpetrator charged for his role in the atrocities.
