By Francisco Jose Diaz Diaz


Mauser

GENERAL:

The 75 mm Krupp mountain gun was a breechloading rapid fire weapon, used by Spanish Army in Cuba. The total weight of the gun was 388 kg, and had a a range of 3850 meters. This gun was capable of firing explosive shell, shrapnel or canister ammunition.

The 75 mm Krupp could be packed on four mules. The first carried the gun tube, the second the trail, the third the wheels, and the fourth the ammunition.
 
 

BACKGROUND:

Brothers Paul and Wilhelm Mauser brought innovative rifle design to Germany in the late 1800's. Specifically in 1892, Paul Mauser introduced several rifle improvements. The most important being a long, non-rotary extractor that prevented double loading and improved in smoothness of operation.

Background:

The 75 mm Krupp was designed by Alfred Krupp and manufactured in Germany beginning in 1895. This gun was a modern breechloading rifle capable of firing smokeless powder. The weapon could be transported to generally impassable areas by being taken apart into major components and packed on three mules. The ammunition would be carried on a fourth mule.

Spanish utilized the 75 mm Krupp gun against the American forces at the action at San Juan Hill. The weapon was also used by Escario's Column during its advance to reinforce Santiago.

Ammunition:

The 75 mm Krupp mountain gun could fire three types of projectiles: shell, shrapnel, and canister. Shell was used against personnel, or fortifications. Shrapnel was an anti-personnel round used at long ranges. Canister was an anti-personnel round used at shorter ranges. All three types of projectiles are loaded into the gun as fixed ammunition.

Advantages/Disadvantages:

The 75 mm Krupp mountain gun was an excellent modern breechloading weapon. It showed good performance during the Battle of San Juan Hill. It was, perhaps, one of the best small guns in that era.

The gun used smokeless powder, an advantage in battle in that the location of the firing gun could not as easily be determined by the enemy without the tell-tale smoke which would issue from a black powder weapon.
