Q : More than 1,000 people owed their lives to the swift action of an animal called "G. I. Joe" in WWI. What kind of creature was he/

A : A pigeon

Actually G.I. Joe was a WW 2 pigeon who is estimated to have saved 1000 or more lives in Calvi Vecchia, Italy. The town had been occupied by the Germans, but an attack by elements of the 169th London Infantry Brigade had taken the town ahead of schedule. In the meantime, a large bombing raid had been organised to pulverise the German defences in and around the town. Due to radio difficulties, the British forces who threw the Germans out were unable to contact their head quarters, so as a last resort, G.I.Joe was sent with a message, arriving just in time to prevent the bombing raid from taking off. Joe belonged to the United States Pigeon Service and accompanied the British, along with his keepers, as liason communications with the USAAF. His timely arrival at the USAAF airfield where the bombers were preparing to take off earned him the Dickens Medal.
