The Folgore (left) suffered very serious damage as the prow of the Bausan (right) penetrated the hull for 1,5 m, bending the propeller shaft. Towed in Naples, the Thunderbolt will be placed in the dock for repair work which will then be continued in Spezia.
The unit will re-enter the 1 October 1890 but efficiency will not be returned to the initial level.
