Why were the Texas Rangers weaker during the civil war?

The Texas Rangers were weaker during the Civil War due to a combination of factors, including the division of their loyalties, as many Rangers left to serve in the Confederate Army. Additionally, the war strained resources and manpower, limiting their operational capacity. The increased focus on larger military conflicts and the need for more organized military units diminished the Rangers' role and effectiveness during this period. As a result, they were less able to function as a cohesive force in Texas.
