Background
With the withdrawal of Japan from the third world war in May, the United States was isolated as a major power in the Union of America. The coasts of the US are surrounded by the Allies in Europe and the Pacific. The Allies launch a major operation to invade the West Coast from occupied Hawaii and Guam, goal is to aid the West Rebellion and liberate states from US control, strengthening the Allied force against the Union forces.

Early Stages
On Day 1, Russian, Chinese and Australian forces assault coasts of the core cities of the United States, including Los Angeles, San Francisco and San Diego. The US Armed forces held the offensives in Los Angeles and San Francisco but failed in San Diego, opening the path to Mexican California. Australian forces advance towards Baja California and liberated cities such as Tijuana and Mexicali.

Late Stages
On September 17th, More Pacific forces are sent to the frontline on Solana Beach. A Russian Offensive is launched in midnight towards Carisbad. Chinese and Australian forces land on the Channel Islands and the beaches of Santa Monica days later. On September 28th, San Francisco is captured by Russian and Chinese forces, causing disarray to the morale of the US armed forces. California is liberated and is merged with Baja California and Sur to form the new Republic of California.

Washington

The American forces held Hillsboro and Portland for 2 weeks until the 28th of September, when the Pacific Allies successfully liberated California. Oregon was entirely captured on the last day of the battle, access to Nevada is imminent and US heavily fortified its borders.
