- "Listen to me! We are survivors! Now they may have got their hands on some of our guns, but that does not make them men! They are animals! We will push them back! Drive them down! And they will not get through these doors!"
After the initial Simian Flu Pandemic ended, the human race plummeted to just 1 in 500 survivors, who were genetically immune and survived the global turmoil that broke out around it. As a result, much of the weaponry that was left behind by the various police and military forces were effectively claimed by a small community within San Francisco. Such weapons included a rocket launcher, multiple machine guns and at least one tank, more than enough weapons to start a small war and kill every ape in the neighboring ape colony if needed. Dreyfus and the human community gathered the weapons and vehicles they could find and kept them under close guard in a storehouse while testing them out in targeting ranges.
Preparation for War
Knowing that the dam warehouse beyond the Ape Village was the only way to restore power to the city, Dreyfus allowed Malcolm to lead an expedition to the village and gave him instructions that if he didn't return on time, Dreyfus would lead his army up to the village and kill all the apes. Dreyfus later took a few men to the armory to test what weapons still work in case a battle arises. Unbeknownst to them, spying on the humans, Koba and his followers discovered the huge collection of weapons and plotted to use them to his advantage for a human massacre.
Koba later returned to steal a machine gun, killed two guards, and framed the apparent death of Caesar on the humans in order to encourage a vengeful attack on the humans. The apes looted the armory storehouse, taking many guns and turned the prepared to engage in a fierce battle. Trying to calm everyone down, Dreyfus reminded them of their will to survive and despite losing some weapons to the apes, they would not let them through the gates.
Starting at California Street, the horseback apes peppered the human army above the gates with gunfire. Dreyfus' people returned fire but losses were suffered on both sides beyond his comprehension, leading to Dreyfus using a rocket launcher to take out several apes near flammable barrels. Dreyfus' army then brought in a tank and gained the upper hand until Koba leaped into the vehicle and drove it into the gates, breaching the defenses and storming the city. Many humans were killed and presumably the least harmful humans were brought into captivity.
Dreyfus escaped capture with a few remaining men and planned to fire C-4 charges, sending a rocketing explosion through an incomplete skyscraper in hopes of killing the apes above for one last chance of revenge. Despite being stalled by Malcolm, he managed to still fire the charges, killing himself and his men.
Following Koba's violent revolution, the apes had caused enough bloodshed and terror that ruined any chance of peace and ignited a war between apes and humans. Although Dreyfus did not live through the battle, any remaining members of his army would likely join the oncoming human armies in the war ahead.
War for the Planet of the Apes: Revelations
- It is unknown how many members of the San Francisco Human Colony are members of Dreyfus' Army, but it can be assumed that only humans who were brave enough or capable of handling firearms participated against Koba's revolution.
- The events of the battle in Dawn of the Planet of the Apes between Dreyfus' human army and Koba's apes are comparable to the events of Battle for the Planet of the Apes. Dreyfus being the counterpart of Kolp and Koba being identical to General Aldo. The battles both end in humiliating human captivity and the deaths of the two army leaders.
