The ACNB officially declared war against the NDSA after the other faction began defensive operations around their borders with the ACNB at Mexico and western Canada. The ACNB formally declared war on the NDSA by a radio nessage from Field Marshall Stapleton. Ten minutes later, BAF forces bombed NDSA troops in Mexico and launched long ranged bombing missions on Vancouver, Seattle and Portland. The missions were suicidal, but caused mass damage to NDSA moral, as well as mass fire damage to Vancouver. The NDSA leadership, as well as that of the Republic of Tennessee, was added to the war crime courts list of wanted fugitives.

The bombing of Vancouver, Seattle and Portland caused damage to the civilian parts of the town creating chaos at first and then rage through out the NDSA territories. The military training centers and outpost were swamped with new recruits itching to get their hands on the ACNB. A cry went out to do the same to them. This cry was ignored by the military command because they did not want to hurt civilians more then what they would have to do. They were American after all. The order for Operation Bullhorn went out.

As the 1st Expeditionary Force hit the Rocky Mountains, the forces in the bunkers and outpost in the Rockies came out and attacked the Canadian army trying to set up a defensive position in the hills. Mortars and gun fire rained down on them. The NDSA air force came in and dropped bombs and strafed the Canadian positions. The 1st and 2nd Air Cav gunships flew over next, attacking and killing at will.

Just north, the 1st and 2nd Air Cav troops were landed on the east side of the mountains and began to set up offensive positions to block any room for retreat. They were soon joined by the gunships to provide cover and reinforce the troops. The transport helicopters took off to start to ferry troops and equipment to the men on the ground. About a half an hour after the last gunship disappeared, the main body of the expeditionary force hit the lines. Although untried they were well trained and motivated, firing every missile and weapon they had. Total chaos enveloped the Canadian lines with the swiftness of the attacks. Snipers took postion on the slopes and began to take out anyone who seemed to give orders.

As the attack on the Canadians in the Rockies continued, a second force moved out of Idaho and through the mountain roads of Montana, coming out on the east side of the mountains and a hundred miles south of Calgary in the province of Alberta. Supporting air forces with this group took off and came screaming in and attacked any ground troops or military instillation they could find in front of the NDSA troops. As any resistance popped up in front of them that wasn't hit by the air force, TMMLRS were pulled forward and launched their brood of missiles at them, creating hell on earth for the defenders.

The Canadians were no match for the NDSA attack on their positions. They were thrown together with the assumption that the NDSA was a pushover and could be defeated easily. There were few veterans in the Canadian forces and they hadn't had time to train their troops. While the NDSA troops were trained and well organized.

The Canadians started to put their weapons down and surrender in mass to the NDSA troops. They were disarmed and separated by rank and then marched west to detention facility's for the duration of the war. Even with the amount of death on the ground the NDSA captured the whole army with several thousand now prisoners of war. It was noticed that they were not nearly as well armed as one would think from a ACNB force. It was assumed they were pretty much cattle being lead to slaughter, which made the NDSA command angry. Orders were given out and the force surged out of the Mountains. They would be on the outskirts of Calgary with in a day.

The NDSA forces south of Calgary were meeting next to no resistance. The would reach the city by the end of the day as well and the city would be surrounded and cut off from the support of the ACNB. Four squadrons of war planes, with two squadrons of bombers took off for the city to bomb and destroy any military fortifications in and around the city. The Canadians retreated from Calgary, allowing the NDSA troops to take the city, and were summarily executed by the SAS troops that they fled to in neighboring towns.

The city of Calgary was taken with little to no resistance. Most of the citizens and solders in the city had little or no heart to commit to fighting the NDSA occupiers. Several of the troops taken as prisoners were more then willing to let all of their knowledge out to the victorious NDSA troops. Several had even eagerly asked to switch sides. Once it was known what the ANCB did to their fellow solders who got away, even more were willing to fight for the NDSA. These troops were separated from their fellows and sent to another camp until a time in witch they could be determine if there was a need for them. As more and more troops and equipment came into the city, the NDSA forces dug in and started to build defensive positions and prepare the city to be a major hub of supplies for the war. A large convoy left Calgary and headed north for Edmonton. Another convoy -- this one consisting of the 1st, 2nd and 5th Air Cav Units -- took off and headed for Saskatoon. Their job was to take the town and its one airport, at which time reinforcements would be sent.

The war ended with the Retreat of the ACNB.
