Its a good strategy, make your enemy run out of ammo and they cant continue to wage war against you.
When the “international brigades” showed up in Spain to fight for the communists, the government wanted to use them in the same way; the problem was that many were “war tourists” with no real military value. They were often persona non grata in their own countries, and briefly found a sense of purpose until the army showed up and quickly set the pace of the war: gradually pushing the leftists into smaller areas, almost never giving back any ground, while starving the leftists of food and supplies. Many were looking for the exit long before the war ended; they were simply a propaganda tool who lost their luster as the atrocities against civilians (especially Catholic clergy/religious) of the side they supported were exposed to the world.
