Italy:
Heavy cruiser
Gorizia at Gibraltar on 25 August 1936, after an explosion of the aircraft fuel stores inside the bow storage spaces the day before
While moored at Tangiers, then an
international zone, to "show the flag" and protect Italian interests in the ongoing Spanish conflict, the heavy cruiser
Gorizia suffered on 24 August 1936 an explosion in the fuel stores (due to volatile fumes) for the ship's aircrafts, located in the bow, which caused no victims, but did cause structural damage to the bow. While the ship was in no danger of sinking, the damage could not be repaired in Tangiers, as it required use of a drydock; Admiral Silvio Salza, highest ranking Italian officer on site, therefore put in a request with British authorities, which granted use of the Gibraltar facilities to undertake basic repairs, to allow the cruiser to sail to Italy. On 25 August, helped by a British tug, the
Gorizia was towed (in reverse, to prevent further damage to the bow bulkheads) to the Rock, and drydocked the day after; on 9 September, the cruiser was able to sail towards La Spezia, reached on 11 September.
This accident offered a unique opportunity for the British, as they were able, by discreetly measuring the hull while in drydock, to deduce that the
Gorizia (and therefore its sisters of the
Zara-class) could not possibly be within the 10'000 tons standard displacement dictated by the Washington Naval Treaty (although they couldn't obviously pinpoint the exact displacement, they estimated that the ship was at least 10% over the limit). Although this technically gave the British government the chance to lodge a formal protest against this violation of an international treaty, it was declined to do so, as at the time policy towards Italy mandated a rapprochement, after the cooling of relationship had during the Italian invasion of Ethiopia.
