|For Autumn's son, see Augustus Autumn.|
After the destruction of the Enclave Oil Rig, Autumn received orders from the new president, John Henry Eden, telling him and all surviving Enclave troops to relocate to the Raven Rock military base on the opposite end of the country. He obeyed the order, gathered his troops and their equipment, and led his men through the post-nuclear United States. Upon the Enclave's arrival in the Capital Wasteland, he was the only one privy to the fact that John Henry Eden is actually a ZAX unit that has achieved self-awareness.
Autumn Senior is mentioned only in the Fallout 3 Official Game Guide.
- "Colonel Autumn has proven to be far less subservient than his scientist father, often openly disagreeing with the president's decisions."
