On 24 October 1893
Cabo Machichaco left Bilbao carrying cargo including iron bars, strips, ingots, and other iron goods, tinplate, flour, wine, paper, tobacco, wood and other items. Her cargo included more than 51 tonnes of dynamite packed in 1,720 boxes, and 12 tonnes of sulphuric acid in 20 glass flasks carried as deck cargo. About 40 tons of dynamite was in her two forward holds, and about 11 tons was in her number three hold. Most of the dynamite was destined for Seville and
Cartagena, but 20 boxes were to be unloaded at Santander. Spanish law forbade any cargo ship to carry more than 43 tonnes of dynamite. And since 1889, the regulations of the Port of Santander restricted the unloading of dynamite to locations as far as possible from the city. It had to be either transhipped to barges off the
Magdalena Peninsula, or landed at piers 7 and 8 at
Maliaño. Unloading it in the main port within the city of Santander was forbidden. In October 1893
cholera had broken out in Bilbao. Therefore
Cabo Machichaco was required to spend ten days at anchor in
quarantine before entering Santander. On the morning of 3 November she entered port, and about 0700 hrs she docked at Pier 1, which was a timber jetty in the centre of the city's waterfront that extended about from the shore. Unloading cargo began about 0800 hrs. 29 tonnes of paper was transhipped to another ship,
Navarro, which was moored nearby. About 1400 hrs smoke was seen coming from
Cabo Machichacos number two hold. Her crew used a pump and hose to fight the fire. Santander's municipal fire service came to lead the fight against the fire. Passers-by started to gather on the waterfront to watch the spectacle. About 1445 hrs seven members of the crew of the steamship
Vizcaya joined the fight against the fire, but by 1500 hrs holds one and two were still ablaze.
Cabo Machichacos
Captain, Facundo Léniz, decided to flood the holds, sinking the forepart of the ship, to extinguish the fire. This would also flood the engine room and stokehold, which would shut down the engine and disable
Cabo Machichacos steam-powered equipment, including pumps, winches and windlass.
ocean liner Alfonso XIII A
Compañía Transatlántica Española ocean liner,
Alfonso XIII, was in port. About 1600 hrs her
Master, Captain Francisco Jaureguizar y Cagigal, with one of his officers and about 40 of his crew came alongside
Cabo Machichaco in a steam launch to help. Members of the crew of other ships then in port also came to help, including from
Pinillos Sáenz's ocean liner
Catalina, British merchant ship
Eden and French ship
Galindo. The effort now was not only to fight the fire, but also to salve items from
Cabo Machichaco in case the fire spread further through the ship. The crew launched her lifeboats to save them from being destroyed. ==First explosion==
