One of the startling aspects of the amazing life of Harriet Tubman is that her life has never been used as a major movie.

Many know the basic facts, that she bravely escaped as a slave in Maryland and then courageously returned — again and again — to lead slaves to freedom. It’s estimated she returned 19 times and freed at least 300 slaves.

That she did this successfully is remarkable. In fact, there was a $50,000 bounty on her head. That’s equivalent to about $1.4 million today.

The Tubman story is told wonderfully in a book written by Kareem Abdul Jabbar. Yes, he’s the great basketball player who late in life has become a successful author.

The book, “Black Profiles in Courage: A Legacy of African-American Achievement,” goes into detail into stories like Tubman’s.

Jabbar describes some of the methods that Tubman used to avoid capture.

If she felt she was being watched too closely, she would buy train tickets heading south, regroup and resume the journey north.

She also communicated with slaves by dressing in disguise. For instance, she dressed as an old slave woman (she was in her 30s) and sang spirituals as code.

Example: “I’ll meet you in de mornin’ When you reach the promised land.”

In 1847 she rescued her own parents.

One legendary story involves Tubman walking through the town of one of her former masters, disguised as an old woman. Figuring she might see him, she purchased some live chickens and carried them on a rope. When her former master came walking toward her, she loosened the rope, the birds escaped and she chased after them.

During her escapes, she was a tough taskmaster. Once on the freedom travels, no slave was allowed to turn back.

What is less known is that she was instrumental in a daring military raid during the Civil War. This raid, like everything else she did, was a success.

She organized an intelligence ring of former slaves. She was able to recruit slaves from areas the Union Army wanted to penetrate.

Tubman led slaves out of bondage, then used the former slaves as scouts.

She led commando raids in Georgia and South Carolina with Col. James Montgomery’s Negro brigade, the Second South Carolina Volunteers.

Her best known raid took place on June 2, 1863, when she led the troops in the Combaheee River area.

Montgomery, Tubman and 300 black soldiers destroyed commissary articles, freed nearly 800 slaves and seized thousands of dollars worth of property.

Almost every able-bodied slave enlisted in the Union Army. By the end of the war, African-American soldiers were serving in large numbers.

In fact:

• There were about 186,000 black troops and 29,000 black seamen on Union vessels.

• By the end of the Civil War, black troops had participated in 449 battles.

• About 37,300 black troops gave their lives in the war.

• About 200,000 black civilians joined support units.

• A total of 17 black soldiers and four black sailors received the Medal of Honor for bravery.

As Frederick Douglass said, “Once let the black man get upon his person the brass letters, U.S. , let him get an eagle on his button and a musket on his shoulder and bullets in his pocket, and there is no power on earth which can deny that he has earned the right to citizenship in the United States.”

These are among the most important untold stories in American history.

It is important that they be remembered.

People like Tubman are true American heroes.
