When his station in the forward dynamo room of the U.S.S. Nevada became almost untenable due to smoke, steam, and heat, Machinist Ross forced his men to leave that station and performed all the duties himself until blinded and unconscious. Upon being rescued and resuscitated, he returned and secured the forward dynamo room and proceeded to the after dynamo room where he was later again rendered unconscious by exhaustion. Again recovering consciousness he returned to his station where he remained until directed to abandon it.
