"A Measure of Salvation" is the seventh episode of the third season from the science fiction television series Battlestar Galactica.

Major Apollo leads a boarding team inside the ship finding most of the Cylons are dead, however, a small group is found barely alive on the bridge.

However, at Captain Helo's suggestion, Admiral Adama orders the prisoners to be brought back to Galactica for interrogation.

Later, he determines the virus to be a strain of Lymphocytic Encephalitis, one that has caused the Cylon's brains to swell and other symptoms like high fever, stupor, and disorientation.

Helo retorts saying that Sharon ("Athena"), his wife and a Galactica officer, has proved her loyalty, risking her neck time and again to help the human survivors and believes there may be more Cylons that think as she does.

Roslin is in favor of the plan, but Adama is uneasy, pointing out that he needs a Presidential Order to use biological weapons.

Roslin takes the responsibility, and orders Adama to carry out the plan to destroy the Cylons with the virus.

The Cylons were in fact killed by Helo, who had secretly sabotaged the air handlers to remove the oxygen from their cell.

James Callis submitted this episode for consideration in the category of "Outstanding Supporting Actor in a Drama Series" on his behalf for the 2007 Emmy Awards.
