Following the American defeat at Onondoga, the surviving American armor division continued the retreat from the city, while under fire from Aztec artillery.
The big debate in the US government continued, over whether to continue the war or to try negotiations.The US government tried to find out whether or not the Aztecs would recognize the independence of Persia if the war ended.Eventually, though, remembering all the terrible things and war crimes that the Aztecs had commited earlier in the war, the US government decided that the Aztecs still needed to be taken down a notch to try to make sure those things never happened again.The American high command then decided to attack in a different direction, and began bombarding the city of Chiconautla in preparation for an attack, while the American armor division was repaired.
A newly constructed American robot also joined the fight against the city.
However, suffering intense Aztec artillery bombardment, the robot was forced to retreat.But American forces continued bombing the city.
The US then lost it's ally.The US government received news that Japan and the Aztecs had agreed on a peace treaty.
Although demoralized by the defeat at Onondoga and the loss of Japanese assistance, the American army, with the fully repaired American armor division, finally moved in for the attack on the city.
After a lengthy siege, the Americans won the battle and took the city, which brought renewed confidence to the American forces on the continent.
After capturing Chiconautla, the American armor division moved further west to scout and see how defended the city of Chengdu was.To American suprise, it was relatively undefended.
The American army immediately proceeded to bombard the city, and the American armor division began attacking the city.Eventually, after being repaired, the American robot joined the fight, and with it's assistance, the city of Chengdu was taken as well.

The US could not understand why the Aztecs were putting up such little resistance.It was wondered if the Japanese had destroyed that much of their army.It was even rumored that the Aztec leader had basically said that the US was defeating them.
Yet even though the war against the Aztecs seemed to be going well, the US now had other fears.The Ottomans had suddenly declared war on the Songhai nation, and quickly took one of their cities.This worried the US government, and it considered whether to become involved in this conflict.But doing so would probably mean a full scale war with the Ottomans on America's home continent.The future was uncertain...
