Why did Erwin Rommel take poison on October 14, 1944?

Erwin Rommel took poison on October 14, 1944, after being implicated in the July Plot—a failed attempt to assassinate Adolf Hitler on July 20, 1944.

While Rommel had been approached by conspirators who suggested he lead the state following Hitler's removal, he was not aware of the assassination plot itself, as he opposed murder for political ends. Following the discovery of his contacts with the conspirators, Hitler sought to avoid the public scandal of a trial for the popular "people's marshal." Consequently, Hitler sent two generals to offer Rommel the choice of suicide by poison, with the assurance that his family would be spared and his reputation protected if he complied. Rommel chose to take the poison, and he was subsequently buried with full military honors.1
