What special problems did the freedmen face immediately after the war? what efforts were made to them?

Problems they faced were coming back to America, without any food and money , also they suffered loss of friends and family who were also in the war. A country usually has to recoup after a war, which usually causes an increase in poverty and homelessness. So summarily the freedman had to build their lives again and adapt to the new environment of America.

It taught people how to live a good life, but not what to believe.
