There were very few major battles on Texas soil during the Civil War. The Union blockaded their ports, and took over the port cities surrounding them when possible. Most of the largest battles that occurred were related to Texas defending or retaking those ports, or crossing their eastern border to delay Union armies marching towards Texas. The Union never actually conquered Texas, and it was a hotspot of blockade runners shipping Southern Cotton to buyers all over the world throughout the war. Texas was in fact still standing as a powerful State with an effective army when General Lee surrendered at Appomattox. Though most of them saw the writing on the wall as the other Southern armies began surrendering.
