English to Spanish Other History Libro sobre el totalitarismo

Only in the Tepelena camp, more than 300 children died. From
1954, concentration camps gave way to hundreds
of camps for life-long internment in remote places
of the country which existed until 1991. In these
camps, families lived in barracks on a few acres of
land where they had to perform labour. Guarded
by armed forces, they had roll calls several times
a day.

P.S. Supongo que se refiere a "to perform forced labour", realizar trabajos forzados, ¿no?
