The Freikorps Lichtschlag was a paramilitary unit in Germany that was established on 14 December 1918 just after the end of World War I.
Armeekorps based in Münster under General Oskar von Watter began to establish Freikorps units out of troops returning from the Western Front.
On 15 April 1919, soldiers of the Freikorps Lichtschlag shot into a gathering of striking workers in the district of Mettmann, resulting in some deaths and injuries.
The unit was against the workers who refused to call off their general strike after the end of the Putsch.
On 16 March its advance was stopped near Aplerbeck by 10,000 men of the Red Ruhr Army, and one day later the Freikorps was defeated.
