After the
Prussian-led
Unification of Germany, the
German Empire with effect from 1 October 1900 established a particular
court-martial jurisdiction () to try soldiers of the
German Army, with the
Reichsmilitärgericht (RMG) in
Charlottenburg as the
supreme court. In Prussia it replaced the
Generalauditoriat agency, while the
Kingdom of Bavaria retained the right to pass judgements to members of the
Bavarian Army by a separate (the 3rd) senate. The presiding judge in the rank of a
general or
admiral was appointed directly by the
German Emperor. During
World War I, Imperial German military courts routinely tried both their own soldiers, POWs, and civilians, who were alleged to have knowingly violated German military law. Whenever the evidence gave them credibility, defense arguments of both
superior orders and also, in contradiction of the Roman legal principle of
Ignorantia juris non excusat, ignorance of the law were often taken very seriously by German military courts in the German Empire, and were sometimes considered grounds for granting leniency. The Prussian Ministry of War also founded a Bureau to investigate allegations of both Allied and
German war crimes, including alleged
Franc-Tireur activity by Belgian civilians, 157 alleged massacres of German POWs by the
French Army on the
Western Front, and the
Baralong Incidents and other alleged
British war crimes on both land and at sea. Following complaints by the
British Foreign Office,
Imperial German Army Sergeant
Karl Heynen, was court martialed for allegedly using unnecessary brutality against 200 British and 40 Russian POWs, who were under his command as forced labourers at the Friedrich der Grosse
coal mine at
Herne, in
Westphalia. Sgt. Heynen stood accused of regularly using
corporal punishment, including his fists and rifle butt and was also tried for having allegedly driven a British POW named Cross insane through various cruelties, including throwing the POW into a shower bath with alternating hot and cold water, for half an hour. It was further alleged that, after a British POW named MacDonald had escaped and been recaptured, that Heynen had hit MacDonald with his rifle butt, knocked him down and kicked him. Also, on October 14, 1915, Heynen stood accused of having threatened the POWs under his command with
summary execution if they did not immediately return to work during an attempted
strike action. Sgt. Heynen was
court-martialed, found guilty, and sentenced to fourteen days' "detention in a fortress", with
suspended sentence until after the end of the war. Heynen was reassigned to
active service at the Front and subsequently awarded the
Iron Cross for courage under enemy fire. At the insistence of the British Government after the Armistice, however,
double jeopardy was set aside and Sgt. Heynen was retried at the
Leipzig war crimes trials for the same offences. Of those enemy nationals who were prosecuted, especially well-known is the case of
Edith Cavell, a
British Intelligence operative under
International Red Cross cover, who was
court-martialled and sentenced to death in
Occupied Belgium for, among many other things, helping an estimated 200 escaped
British POW's to cross the lines and return to
active servicewhich in wartime was indeed a
death penalty offence for civilians under the German military law in the
German Empire. Cavell was also convicted of
perfidy, for having used the international legal protection given by her position as a Red Cross nurse as a cover for violating
medical neutrality during wartime. Cavell was executed by
firing squad in Brussels on October 12, 1915. Belgian national
Gabrielle Petit, a fellow British Intelligence
field agent for
La Dame Blanche spy ring in occupied Belgium, was similarly court-martialed as a
civilian subject to service discipline, convicted of espionage, and executed by firing squad on 1 April 1916. After his civilian merchant ship was captured off German-occupied Belgium, English captain
Charles Fryatt was
court-martialled by the
German Imperial Navy for "illegal civilian warfare", "being a
Franc-Tireur", and attempting to ram and sink
SM U-33 on 28 March, 1915. The trial, verdict, and
death sentence were also covert retaliation for
Winston Churchill's orders to both the
Royal Navy and British merchant seaman to unleash
total war against U-boat crews, which had already resulted in one of the most infamous
British war crimes of the Great War, which also led directly to the German Admiralty's decision to adopt
unrestricted submarine warfare: the 19 August 1915 massacre by the Royal Navy of the shipwrecked crew of
SM U-27 in the
Baralong incidents. Charles Fryatt was executed by a Naval firing squad in Bruges on 27 July 1916. == Nazi Germany ==
