"Braving severe Alaskan weather and with a low ceiling forcing his plane to fly through clouds to carry out its attack mission against Japanese ships in Kiska Harbor, Ensign Keller skillfully assisted in determined dive-bombing and strafing attacks. Pulling out in the clear at a very low altitude, his plane was subjected to withering antiaircraft fire from enemy ship and shore batteries and pierced by shrapnel and lighter caliber projectiles."
