Yvonne Hartman
I did my duty, for Queen and country!
Yvonne Hartman was the administrator of Torchwood in 2007, prior to the Battle of Canary Wharf. She presided over the long-awaited capture of the Doctor.
Profile
Hartman oversaw the projects that included the investigation of the Void Ship, as well as the ghost shift experiments that resulted in the invasion by the Cybermen from the alternate dimension, Pete's World. She was not personally hostile to the Doctor, yet she was confident in the righteousness of Torchwood's actions to the point of fault, ignoring his recommendations and warnings. Hartman was fiercely patriotic, and believed that Torchwood's work was vital to the survival of the "British Empire" and was assured that their work would in fact lead to the restoration of the United Kingdom to the status of world power. Only when the end was near did she attempt to stop the experiments, only to find that the Cybermen had already taken control over key members of her staff. The controlled staff proceeded to override her orders and allow the Cybermen to continue their invasion. (DW: Army of Ghosts)
Ultimately, she was seized by the Cybermen and "upgraded" into another Cyberman. While still stricken with tears, she walked into the chamber without coercion, claiming that she "did [her] duty for Queen and Country".
However, Hartman somehow managed to gain complete control over her new metallic body and performed one last known service, fending off the Cybermen approaching the top offices long enough for the Doctor and Rose Tyler to seal the breach between worlds. While fighting against the Cybermen she continued to utter the phrase "I did my duty for queen and country" while crying oil. Her ultimate fate is unconfirmed: she may have been killed or been sucked into the void with the rest of the Cybermen or remain hidden on Earth, as she was not covered with "void stuff" so shouldn't be sucked into the Void.
