Is it possible to create an event mod where if the CSA captures the CA ports, an event triggers where trade all the sudden is a lot less restricted, and foreign intervention is increased due to the free pacific (except the pacific fleet)? Getting these ports were Sibley's top priorities for this reason. I just thought it to be a nice addition to give the player a more dynamic/competitive stance in the Far Western theater, besides the player completely abandoning it to avoid the Union from achieving VP in places like Arizona.
"For years, residents in the southern part of the New Mexico Territory had been complaining that the territorial government in Santa Fe was too far away to properly address their concerns. The withdrawal of the Regular army at the beginning of the war confirmed to the residents that they were being abandoned. Secession conventions in Mesilla and Tucson voted to join the territory to the Confederacy in March 1861, and formed militia companies to defend themselves.[9][10] In July 1861, Lieutenant Colonel John Baylor led a battalion of Texas mounted rifles into the southern portion of the New Mexico Territory, entering Mesilla and repulsing the attack of the Union garrison of Fort Fillmore at the First Battle of Mesilla. The victorious Baylor established the Confederate Territory of Arizona south of the 34th parallel.[citation needed]
The 1862 campaign was a continuation of this strategy formulated by Sibley in a plan presented to Confederate president Jefferson Davis. Sibley's strategy called for an invasion along the eastern side of the Rocky Mountains, seizing the Colorado Territory (then at the height of the Colorado Gold Rush) and Fort Laramie (the most important United States Army garrison along the Oregon Trail), before turning westward to attack the mineral-rich Nevada and California. He planned to take minimal supplies along with him, intending to live off the land and to capture the stockpiles of supplies at Union forts and depots along the Santa Fe Trail. Once these territories had been secured, Sibley intended to take the northern Mexican states of Chihuahua, Sonora, and Lower California, either through purchase or by invasion.[11]"
Brig. Gen. Henry H. Sibley, a former regular army officer serving in New Mexico, resigned his commission and traveled to the Confederate capital to present such a plan to Jefferson Davis. Sibley proposed to lead a mounted force to New Mexico, live off the land, defeat the Federal forces encountered and secure the military supplies and natural resources of the territory (encompassing modern New Mexico and Arizona, as well as part of Nevada) for the Confederacy. He would then march north, capture the rich mines of the Colorado Territory and proceed west through Salt Lake City and across the Sierras to occupy the California seaports of Los Angeles and San Diego. In one stroke, Sibley would bring the entire Southwest, its gold and silver and the terminus of the transcontinental railroad under Confederate control. Though farfetched, the scheme cost the Southern treasury little and retained the possibility of a sizable return. It was approved, and Davis commissioned Sibley a brigadier general, giving him authority to raise a mounted brigade in Texas for the campaign.
