December | WWI Model “A” Field and Camp Telephone
This artifact is a World War I-era Model “A” Field and Camp Telephone. The phone features an oak wood case with a black metal hinged cover. Inside the case are the hand set and the battery that powers the phone. When in use, the hand set can be hung on a hook situated on the outside. The outside also has a speaker and a crank, the latter which can be wound to generate power to charge the battery. A leather carrying strap is attached to the case, and adorning the top is a brass plaque that reads “Camp Telephone Model A Signal Corps US Army.”
These telephones were used on the battlefield to communicate directions among troops, allowing the coordination of much larger armies than had been previously possible. Although sometimes they were connected to existing civilian telephone wires, typically Army forces would string their own communication wires, known as outpost wire, through which these phones could be connected.
At one point during World War I, the Army estimated the need for outpost wire to connect these phones to be 68,000 miles worth per month. During both World Wars, telephones were preferred over radio for communication, which was usually reserved for mobile units or situations where wires were not yet in place.
