The Battle of Rose Hill was an attempt by Eric Savin and Ellen Brandt to kill Tony Stark.
Tony Stark was assumed dead after his house was destroyed with him inside. He managed to escape and his armor followed a previously calculated flight plan to Rose Hill, Tennessee.
Delirious, hungry, and exhausted, Stark was found in the garage of Harley Keener, who eventually helped him to find Mrs. Davis, a local whose son mysteriously exploded, killing five others in the blast.
Mrs. Davis had been called by Ellen Brandt who asked her to meet her at the local bar and bring the file and videotape that Chad had made about his experiences with A.I.M. and the Extremis formula which its company's founder, Aldrich Killian, was using on amputated veterans.
