Raid on Porto Buso
The raid on Porto Buso was an assault launched by the Italian Royal Navy on an Austro-Hungarian naval station and border post located in Porto Buso island, in the Marano-Grado Lagoon, in the first hours of 24 May 1915, the day when the Kingdom of Italy entered World War I on the side of the Entente. The incursion became the first offensive action of the Italian Navy in the conflict, and ended with the destruction of the naval outpost, the sinking of a flotilla of small vessels and the capture of the majority of the Austro-Hungarian garrison.
