Slaughter of the Steps

The Slaughter of the Steps, also known as the Ephesus Massacre or The July 28th Massacre was a warcrime committed by the cities Katigadis, in which 4,417 civilians died.
HWS Ephicheris had mutinied on July 2nd against their officers, and on July 28th engaged HWS Dynami, a torpedo ram, off the cost of Ephesus during widespread protests against the execution of Eresu prisoners of war following the Battle of New Viserothis. Epicheris destroyed the Dynami leading to cheering from the Gorathics assembled on the famous city steps. Katigadi troops, who had been ordered by Governor Lusitanis Astophisis to maintain order and but down any riots, opened fire on the crowd and began a massive rout, systematically slaughtering and preventing the escape of those on the steps. Before Hybretian Regulars could restore order, civilians had taken up arms in other parts of the city, and the steps ran red with blood.
The Novacian Government was the first to learn of the massacre, to the surprise of the Hybretian Government who had not been able to contact the Ephesus telegraph station for nearly a day. Hybretia ordered an immediate investigation to determine what happened after it was revealed Kordynian, Setacoline, Kolanski, and Novacian merchants and tourists, as well as Kygonese citizens, had been slaughtered on the steps. In all, 31 of the estimated 515 Katigadis believed to be responsible were captured alive and publicly executed. 
Following the attack, HWS Ephicheris shelled the city's Military Command and killed the Governor and most likely many of the Katigadis responsible. 
The foreign dead were delivered via destroyers to their homelands with honor guards. Following the events, the Novacians attempted to assassinate Emperor Basilean, sparking the Hybro-Novacian War.
