May 4, 1917 - Australian Cruiser Battles vs. Submarine and Zeppelin

Pictured - An air-sea melee.

A confusing sea and air battle took place on May 4, 1917. The Australian cruiser Sydney, in concert with the British cruiser Dublin and four destroyers, engaged a German Zappelin flying near the Fyrth of Forth. Suddenly, two German U-boats also engaged the Royal Navy ships, turning the battle into a surface-air-undersea melee. By 2:30, after inconclusive fighting, both sides ran out of ammo and returned home with no casualties.
