And you're not? Where did that info about prisoners of war come from? post a link.
There were wars between tribes. Captured prisoners were sold to slave traders. The slave trade may have added fuel to the fire, but these intertribal wars existed long before the traders.

WHO AND HOW MANY PEOPLE WERE ENSLAVED?
People often became slaves for reasons rooted in local disputes, and
wars; or they became slaves as a demonstration of wealth and power
on the part of a local ruler. However, enslavement at a local level
could often lead to a chain reaction of sales from merchant to
merchant ending up at the coast where the final sale resulted in being
dispatched across the Ocean.
WAR
A large number of people began the journey into slavery as prisoners
of war. The Baganda in East Africa, for example, often went to war with
their neighbours and took Bunyoro and Basoga people as slaves.
With the rise of a large commercial slave trade, driven by European
needs, enslaving your enemy became less a consequence of war and
more and more a reason to go to war. This was particularly so in West
Africa where, for example, the conflict between the kingdoms of Oyo
and Dahomey resulted in prisoners of war being taken as slaves on
both sides and then sold on to the coast.
PUNISHMENT
Some people were taken into slavery as a punishment. The crime
might be witchcraft, theft, or adultery.

....European traders such as Nicolas Owen waited at these forts for slaves; African traders transported slaves from the interior of Africa. Equiano and others found themselves sold and traded more than once, often in slave markets. African merchants, the poor, royalty -- anyone -- could be abducted in the raids and wars that were undertaken by Africans to secure slaves that they could trade. The slave trade
devastated African life. Culture and traditions were torn asunder, as families, especially young men, were abducted. Guns were introduced and slave raids and even wars increased.
Like all traders at the time, Owen
did not capture slaves himself; rather, it was Africans who acquired slaves and traded the captives for various European goods. Sometimes the captives would be
prisoners of war. Other times, groups would venture deep into Africa's interior for the sole purpose of capturing slaves.

Africans were captured as slaves by other
Africans in the following ways: prisoners of
war, slave raids, condemned criminals,
condemned debtors, persons accused of
witchcraft, kidnapped. In any one region and
time slaves were created by a mixture of these
methods, but one or two tended to
predominate at any time and place. In the
Senegambia, Guinea Coast, and Slave Coasts of West Africa,
war tended to predominate as the most important source of
slaves. In places like Angola enslavement by kidnapping and
condemnation for debts was quite important. Slaves were
almost always captured in situations of conflict. Sometimes,
if a family member learned of the capture of one of its
members, it could bargain with the person who had enslaved
him or her to redeem (purchase) the slave back Sometimes
families traded a slave they themselves owned for a member
of their family. This practice, which occurred in many places
in Africa, was symbolic of the great tragedy of the slave
trade. In order to save members of their own families, many
persons engaged in capturing others.
