Paraguay's War of the Triple Alliance - 1864 to 1870

While listening to a podcast, I cam to learn about Paraguay's War of the Triple Alliance.

War of the Triple Alliance - Wikipedia, the free encyclopedia

The specific numbers of casualties are hotly disputed, but it has been estimated that 300,000 Paraguayans, mostly civilians, died; up to 90% of the male population may have been killed. According to one numerical estimation, the prewar population of approximately 525,000 Paraguayans was reduced to about 221,000 in 1871, of which only about 28,000 were men. Definitively accurate casualty numbers will probably never be determined. After the war, the Catholic church temporarily allowed polygamy to help repopulate the country.

Is it just me or are we getting better (fewer losses) at this war thing?
