Besides armed resistance, other forms of resistance to the Nazi German occupation were carried out by the Dutch. These were important options for those who opposed the Nazis but chose not to use weapons. Nonviolent resistance included spying, going into hiding and aiding fugitives, not following Nazi rules, attending public protests, publishing illegal papers, and sabotage (destroying) companies aiding the war effort. Thousands were arrested by the Nazis and jailed for months, tortured, sent to concentration camps, or killed.
