In 2155, Lundy was stationed on the Earth colony Tarod IX when the planet was attacked by Romulan forces shortly after the start of the Earth-Romulan War. The fighting was fierce and the majority of the civilian settlers and MACO forces were killed. After the attack, the Enterprise (NX-01) arrived on the scene and rescued the survivors, including Colonel Lundy.
Captain Jonathan Archer invited her and Yutaka Shima to dinner aboard the ship, but the discussion turned heated right away. Lundy and Shima were resentful for Starfleet's slow response and refused to eat anything that wasn't provided to the civilian survivors of the attack, eventually walking out on the dinner.
