The 370 Raid was an attempt to bypass the state of the economy to pay the 370 team.
The economy of the New California Republic was struggling to pay its workers. Porter, as foreman of his mining team, the 370, became increasingly concerned over the likelihood of being able to pay his workers and decided to take the extreme measure of rallying them together in preparation to raid the NCR Storehouse and Bank.
Porter led 370 team to the NCR Storehouse and Bank, where they set explosives and blew the vault open. Before the money could be taken officers of the NCR swiftly appeared on the scene, thanks to D.C. Lowery tipping off Lt. Gov Dodge out of the fear he would not be paid either way. The 370 team workers were subdued and arrested.
After their arrest the members of 370 team faced the threat of torture and branding in the NCR prison system. In 2249 Lt. Gov. Dodge, under the impression Porter knew where the money was, organized a break out for 370 team hoping Porter would loop around and attempt to recover the money, but it only resulted with another worker team, the 308, escaping.
Despite 370 team not actually taking the money, it was left vulnerable, and still disappeared from the vault, totally ruining the chances of economic recovery. The civilization that is NCR entered a slow death.
