When the American Civil War began, Tubman worked for the
Union Army, first as a cook and nurse, and then in Army Intelligence as an
armed scout and spy. As an Army Intelligence Officer she was the first woman to
plan and lead an armed expedition in the war, she guided the Combahee River
Raid, a union army commando raid which liberated more than 700 slaves in South
Carolina and destroyed a critical ammunition supply depot of the Confederate Army.
When she died, Tubman was buried with military honors at Fort Hill Cemetery in
Auburn.
