The Russo-American War, also known as the Invasion of America or the Second Great Patriotic War by Russia, was a large conflict fought on a scale not seen since World War II. The initial invasion was the largest in military history, with almost four million Russian (and other allied) troops taking part, against some initial troop numbers with less than three million American defenders. Ultimately, Russia, collaborators, and allies fielded some nearly nine million combatants, while the American government and independent groups responded with around eleven million troops. The conflict raged on for five years, from 2021 to 2026, and resulted in more than seventy million casualties overall, being the deadliest conflict in history, surpassing World War II.
The invasion began in 2021, with the Russian military and a few allied units striking key cities on the east and west coasts of the United States. This resulted in the battles of New York, Boston, Seattle, Los Angeles, and several others. It saw initial Russian success, with the cities being taken and much land being secured around them. Additional ground forces were then moved in by Russia and allies. By early 2022, offensives were in full operation, going on on the east and west coasts against the shocked and demoralized defenders. Foreign volunteers aided the US forces, and meanwhile American collaborators fought alongside Russia. By 2023, most of the coastal states were taken and Russian forces pushed further inland.
During that time (in mid 2022), a Russian military administration, known as the Territory of the Military Commander in America, was formed, which oversaw overall management of conquered territory. After speaking with defected General Dan Allyn, Colonel General Nikolai Makarov agreed to set up the American Provisional Administration, which oversaw day-to-day management of the occupied territories on the east and west coasts. They set up a military force of collaborators, called the American National Militia. As Russian forces pushed further inland, the Independent State of California and Republic of Texas were formed as puppet governments. Alaska was annexed into Russia, becoming the Alaskan Federal District.
By 2024, much of the Midwest fell to allied troops, with US loyalists holding out in the central states of the country. They held out and slowed the allied advance. For several months it was a statement, until India offered to bring in additional troops, turning the tide in the allies' favor. The US attempted one offensive during this time, but it failed and caused heavy losses. The US navy particularly was heavily hit, many of its vessels were captured as the coasts were taken.
