Action of 4 May 1917

The action was inconclusive with no casualties on either side, concluding when the Zeppelin had dropped all of its bombs and the cruisers had expended all of their anti-aircraft ammunition.

This was followed by a further attack on Sydney, with between ten and twelve bombs being dropped but missing due to the cruiser's evasive manoeuvres.

The Zeppelin was forced to remain high to stay out of range of the anti-aircraft fire, this meant that the bombs were dropped from too great of height to strike the Allied patrol.

[6] The action was commemorated in the early 1930s, in an oil painting by Australian war artist Charles Bryant.

[7] It was the first time that a Royal Australian Navy vessel had been attacked by an aircraft and was one of the actions that resulted in Sydney being awarded the "North Sea 1916–18" battle honour.
