From I. Ehrenburg's article «Kashtanka», published in the newspaper «Krasnaya Zvezda» on May 25, 1942.

"How can one not remember the red-haired Airedale Terrier, Kashtanka? Wounded in the head, with a torn ear, bleeding profusely, Kashtanka crawled to her leader: she delivered a report to the battalion…
A messenger dog is devoted to duty; neither a bullet, nor a bird in the bushes, nor death will stop it: it hurries with its message.
While our troops were defending Krest Hill, Freya the Airedale made 33 trips covering 70 km. On her last trip, Freya returned mortally wounded: a mortar fragment shattered her jaw.
What can I add to this simple story? In war, people more than ever value loyalty."
