Continued Comanche raids led to the election in 1838 of Mirabeau B. Lamar who favored a more aggressive approach. The massacre of 12 Comanche chiefs attending a peace conference in San Antonio in March 1840 set off a series of bloody reprisals and battles. Hundreds of Comanches descended upon and destroyed the towns of Victoria and Linnville in 1840 (see Great Raid of 1840). Although the Texans demonstrated they could defeat the Comanche (See Battle of Plum Creek), military campaigns emptied their treasury and Texas became more accommodating. (See Texas-Indian Wars) In 1844, the Texans and the Comanches came to an agreement which recognized Comanche lands and left Comanchería intact.
