Sometimes modifications are done by accident. On the night of February 7, 1943, Commander Howard Gilmore in Growler collided with an attacking Japanese gunboat. In the event Gilmore was badly wounded and two other bridge personnel were killed. Gilmore, knowing he could not make it below and that hesitation on the part of the crew would mean the possible sinking of his ship, ordered the boat submerged with him still outside. The bow of Growler was bent 90 degrees to port in the collision. The bent bow was cut off and replaced with another bow to effect repairs. Gilmore received the Medal of Honor for his selfless act.
