American-Union War

The American-Union War, also known as the War of Union Aggression, was fought between 1940 and 1941 between the Franco-British Union and the United States of America.

Following the dissolution of the Neutrality Agreement, by Kermit Roosevelt, it was thought by the Franco-British Union that the United States would join the Central Powers in light of the acceptance of the CSA into the Allies. In mid-1940, Field Marshal Bernard Montgomery reasoned with the parliament that they cannot allow an ally of Germany within the Americas in fear of opening a second front with the Central Powers and sought out a way to prevent the Americans from ever joining the Germans, as well as finding a use for the dragons captured after the Berlin Incident.

Winston Churchill, on his own initiative, sent an insulting and extravagant ultimatum to the United States to accept the CSA as the legitimate owner of the southern part of North America and return to the neutrality agreement. Upon its rejection, the Franco-British Union invaded from Canada while their CSA allies only observed from the south. The war is notable for several particularly bloody battles, including the Battle of Wales, which saw the British use the Dragon Corps against the American forces. The Americans eventually won the war, occupying Ireland and joining the Central Powers.
