This was the conflict that triggered the separation of the Yellow and the Tan, which ends with the total extermination of the original Yellow Nation.

The Tan took over the Yellow Nation, putting 85% of the Yellow Army in the Thermopiles passage, attacking them in mass. 1/4 of the Yellow Army escaped through the narrow passage, saving a few, but meanwhile the secret allies of the Tan, the Greys, were waiting on the other side, finishing the Yellow forces there.

However, this entire joint maneuver between the Grays and Tan, which achieved the total and complete independence of the Tan, cost them dearly: Losing all the raw materials for Yellow plastic production.
