In the "struggle for hegemony in the Mediterranean" between the Ottoman Empire and Spain, Toledo artillery was deployed in Sicily, Naples and other places controlled by Spain.

The flint gun was invented by Mahan, a Frenchman who was born in 1547 (the middle of the 16th century) in the family of a gunsmith, locksmith and watchmaker. It was improved on the basis of the revolver gun. The spring steel wheel was removed, a piece of flint was clamped on the jaw of the hammer, and a striking anvil was set beside the fire hole. When shooting, the trigger was pulled. Under the effect of the spring, the flint was heavily hit on the side of the fire door, and sparks came out to ignite the gunpowder. Greatly simplifies the shooting process, improves firing rate and shooting accuracy, is easy to use and cost-effective, and facilitates mass production. European armies were generally equipped with flintlock guns, which lasted for over 200 years until 1848.
