Although the odds were against in the death camps, some managed to live. How could these people survive against overwhelming odds?

It honestly depends on their personal situation. Some may have gotten away or looked over (extremely rare and lucky), and some may have just survived.

The body is insane and will do anything keep us alive - that's it main job. Some people who go into shock manage to survive, as their body shuts off any unneeded parts - mental awareness, etc. Some people also may have just gotten lucky, and their bodies may have lived through what they went through.

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.

for the united states of america, 1945 to 1964 was a time of high economic growth and general prosperity. it was also a time of confrontation as the capitalist united states and its allies politically opposed the soviet union and other communist countries; the cold war had begun.
