This is a French double-loaded 240mm/L-45 coastal gun, located in Dakar, the capital of French West African colony. It is said that Dakar has deployed nine 240mm guns (that is to say, the guns also have a single turret version) to build a powerful coastal defense system. These French heavy guns are the auxiliary main guns of the extended "Dandong" class battleship. In the Dakar incident, the British army suffered a little from the 240 mm coastal gun. Although Hong Kong's battleship Bishop's eight 380mm main guns were more powerful, this ship, which fought alone overseas, did not have much ammunition when it escaped from the French mainland because it could not get ammunition supplies. Therefore, the captain Colonel Mazen carefully saved ammunition and fired a volley at the British ship, without giving full play to the long-range advantage of Schneider's 380mm naval gun. Therefore, most of the fire suppression tasks of the French defenders on the British battleships are undertaken by the 240 mm coastal guns in the port. Although it is difficult to penetrate the main armor of battleships "barham" and "Determination" from a long distance, sweeping the deck and superstructure is still extremely threatening. There were many 240mm shells in the hull of the barham, and at the same time, the Determined was successfully attacked by a French submarine torpedo. Only then did the British get angry.

A Brazilian dual 305mm coastal gun seems to be located in Rio. It's not clear where the gun came from. I don't know if it was bought from England alone, or if it was a relic of naval guns misappropriated after two "Minas, Gila" class battleships retired.

Before 1930, Spain purchased a batch of 1926 38 1mm coastal guns from Britain, which were scattered in important ports such as Cartagena, Cadiz and Seville, and some heavy guns were still in service. The picture above shows a test shot in Cartagena in 2007, which is also the "Iowa" of the United States.
