Why did sam Houston try to replace Felix Huston with Albert Sydney Johnson?

Sam Houston sought to replace Felix Huston with Albert Sidney Johnston primarily due to concerns about Huston's leadership and military effectiveness. Huston had faced criticism for his tactics during the Texas Revolution, and Houston believed that Johnston, with his more extensive military experience and reputation, would better unite and strengthen the Texas army. Additionally, Houston aimed to instill a sense of discipline and strategic planning in the forces, which he felt was lacking under Huston’s command.
