Svild

Svild was a Sontaran soldier during the time invasion of the Crimean War.

Biography
At some point, he was sent by Commander Skaak to spy and assess the British Army, when he was injured by a cannon ball to the back, and brought to Mary Seacole's British Hotel. The Doctor arrived and told Svild she would reveal the whereabouts of the Sontaran's greatest foe, the Doctor, if he would convince Skaak of a parlay with her. Svild accepted, and was released to return to the Sontaran encampment, behind a camouflage shield. He told Skaak the information, but was "mercifully" executed for his shame.
