From Marvel Wikia:
General Phillips hand picked 4-F army reject Steve Rogers to become a part of the 1940 Operation Reborn experiment. In particular, he admired Rogers patriotic spirit. Later, Phillips was a part of picking Rogers as the eventual Super-Soldier Captain America. Phillips also oversaw Rogers initial training as well as some of his early missions.
After the fact, Phillips was aware that an unauthorized military group gave the Super Soldier Serum to Protocide, prior to Steve Rogers. As he displayed no life functions, Phillips believed Protocide to be deceased and the General dealt severely with the perpetrators through military channels.
Phillips was a hard nosed commander who did not tolerate errors from his charges. Phillips eventually retired from the military and lived a long life. He was killed in a rest home in Kentucky. He and Captain America were attacked by Lemurian assassins. While battling his assailants, General Phillips throat was fatally slit.
