Goetic Revolution

The Teutonic Revolution was a multi-party civil war within the former Teutonic Empire from 1924 to 1925 near the end of the Grand Campaigns. The largest belligerents were the incumbent Teutonic Empire; the Red Collective (colloquially referred to as the Reds) including the self-proclaimed Socialist Republic of Teutonia plus several smaller communist and anarchist groups; and the Liberal Coalition which principally consisted of the self-proclaimed Free Republic of Teutonia and later Austrasia. Occuring concurrently with the Grand Campaigns, battles between Teutonic imperial, Crown Alliance, and republican forces merged with engagements connected to the civil war. The Crown Alliance generally acted in support of the Red Collective, having covertly supported their build up earlier in the Grand Campaigns as a means of weakening Teutonia. Meanwhile, the republicans supported the Liberal Coalition.

The conflict resulted in the end of the Teutonic Empire. The monarch of Teutonia Frederick IV was executed by communist militants in Oberlandscheid on 15 August 1924. Following this, communist militants continued to fight imperial loyalists, as well as the liberal revolutionaries and republican forces, until a truce was signed on 7 June 1925 ending the revolution and combat in the Grand Campaigns' West Artemian Theatre. It ultimately resulted in the creation of the Socialist Republic of Teutonia, Austrasian Riche, and cessation of some lands to South Boaga and Agrana y Griegro.

Fall of Oberlandscheid
By July 1924, Tiperyn and Koryese forces had advanced deep into northwestern Teutonia following their successful Zahner Offensive earlier in the year. Crown Alliance forces had advanced to the Wilge River, linking with Teutonic communist revolutionaries and surrounding the capital of Oberlandscheid on three sides. The combination of renewed offensives by both the Crown Alliance and Republicans, as well as attacks by Teutonic communists, had battered the Teutonic army in the north and heavily damaged its rail infrastructure. At dusk on 2 August 1924, the Tiperyn No. 1 Mechanicalized Regimental Group, No. 14 Lorried Rifleer Regimental Group, and Koryese Black Flag Army completed the encirclement of the Teutonic capital, trapping the Teutonic V. Corps inside the city limits. Reinforced with Tiperyn theatre-level artillery regimental groups and an additional three division-sized units by 6 August 1924, communist militants began their assault on the city in earnest.

While receiving heavy artillery support from the Crown Alliance, Tiperyn and Koryese forces did not enter the city until 13 August. The delay has been attributed to an unwillingness by the Tiperyn expeditionary corps commander to risk substantial casualties at that point in the battle. Rather, it had been the Crown Alliance's strategy to allow the communist militants to soften up Teutonic loyalist forces and conduct risky reconnaissance missions in order to both spare friendly forces and wear down the communists. This is due to the fact that it was not expected by military planners that the communist revolutionaries would remain active following the Zahner Offensive. Rather, they were intended to be a temporary means of striking critical infrastructure behind enemy lines in the lead up to the 1924 offensives.

Two days after Tiperyn and Koryese forces entered the city, communist militants stormed the Imperial Palace at the heart of Oberlandscheid. Frederick IV was captured on 15 August after a brief firefight in the fortified palace and summarily executed by communist forces. Although Tiperyn and Koryese command had wished to capture the Teutonic monarch alive in order to negotiate a ceasefire, local Crown Alliance commanders allowed for the communist forces to lead a purge of the city's federal institutions. The city was officially secured by 5 September.
