Spanish ship Real Carlos (1787)

Real Carlos was a 112-gun three-decker ship of the line built at Havanna for the Spanish Navy in 1787 to plans by Romero Landa. One of the eight very large ships of the line of the Santa Ana class, also known as los Meregildos. Real Carlos served in the Spanish Navy during the French Revolutionary Wars and was destroyed with heavy loss of life during the Second Battle of Algeciras.

Construction
The Santa Ana class was built for the Spanish fleet in the 1780s and 1790s as heavy ships of the line, the equivalent of Royal Navy first rate ships. The other ships of the class were the Santa Ana,  Mexicano, Salvador del Mundo,  Conde de Regla,  San Hermenegildo, Reina María Luisa and Príncipe de Asturias. Three of the class were captured or destroyed during the French Revolutionary Wars.

History
In 1793 was under the command of Baltasar Sesma y Zaylorda as the flagship of Admiral Francisco de Borja. Borja led an expedition to Sardinia, capturing the islands of San Pietro Island were taken and Sant'Antioco to the French.

On 8 April 1799, Real Carlos was flagship of the Ferrol squadron under Francisco Melgarejo, alongside Argonauta, Monarca,  San Agustín,  Castilla and three smaller ships. This squadron sailed in an effort to unite with the French Atlantic Fleet operating in the Croisière de Bruix, but missed the rendezvous and spent the much of the rest of the year at anchor in Rochefort, returning on 11 September. The following year Real Carlos participated in repelling the British Ferrol Expedition.

By July 1801, Real Carlos was at Cádiz. When a French squadron defeated a British force at the First Battle of Algeciras on 6 July, Real Carlos joined the squadron sent to escort the French from Algeciras back to Cádiz. During the night of 12 July the combined force was returning through the Straits of Gibraltar when a British squadron attacked them at the Second Battle of Algeciras. During the confused night action which followed, HMS Superb cut through the rearguard and between Real Carlos and San Hermenegildo. The Spanish ships opened fire, striking one another, as a fire spread across Real Carlos ' s decks. In the darkness the two huge Spanish ships collided, fire spreading out of control until both exploded in a fireball that could be seen from shore. More than 1,700 men were killed in blast, one of the greatest losses of life at sea to that time.
