What was so brutal about Leopold's actions in the Congo?

Explanation:

Leopold II implemented a forced-labour system in the Congo that was quickly copied by other European colonial powers. This brutal practice was a catastrophe for the population of the Congo, and Leopold was eventually forced to give up his hold on the colony.

Leopold used slave labor to benefit only himself, he commited genocide, and he would have the hands of his workers cut off if they were not working fast enough.

union blockade

explanation:

the union blockade in the american civil war was a naval strategy by the united states to prevent the confederacy from trading.

the blockade was proclaimed by president abraham lincoln in april 1861, and required the monitoring of 3,500 miles (5,600 km) of atlantic and gulf coastline, including 12 major ports, notably new orleans and mobile. those blockade runners fast enough to evade the union navy could only carry a small fraction of the supplies needed. they were operated largely by british citizens, making use of neutral ports such as havana, nassau and bermuda. the union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.
