Between 1526 and 1867, slave ships took around 12.5 million slaves from Africa to the Americas.[1] Conditions were horrible, and around 1.8 million slaves died along the way.[1] This was the deadliest migration in human history.
Conditions
Living conditions for slaves on these ships were awful.[2] Men, women and children were crowded into every possible space, leaving no room to move or even breathe. There was little food, fresh water, or fresh air, and the smell was terrible. Sickness was widespread.
Sometimes Africans were kept on deck chained together with long chains. Sometimes they would jump overboard, taking every other chained slave with them, to avoid their unknown fate. Many ships kept extra crew members on deck to prevent this from happening. At other times crew members would throw slaves overboard as a warning to other slaves.[3] If the ship was running out of food or water, all the slaves would be killed to save the crew from starving.[3]
On average, it took 60 to 90 days to sail across the Atlantic.[4] However, some journeys took up to four months.[4]
Slaves being thrown overboard to drown, like in the Zong massacre
Sometimes, slave ships could get insurance on their slave cargos .[3] But insurance would not pay out for slaves who were sick or starving. However, they would pay if the slaves drowned.[3]
In 1781 the slave ship Zong was hauling 470 slaves—more than the ship could handle.[5] Many began to get sick, and disease spread. By the time the ship reached the Doldrums, a mid-Atlantic region that at times had no wind, several of the crew had died from diseases.[5] To save themselves, the remaining crew threw 132 dying and sick slaves into the ocean.[5] Another 10 slaves jumped with them.[5]
When they tried to collect the insurance the insurance underwriter denied the claim.[5] In 1782 a court in Jamaica ruled for the owners.[5] The insurance company appealed the decision, and this brought a good deal of public attention.[5] It began to be called the Zong massacre.[5]
No member of the crew or the owners were ever charged with murder.[5]

Slave ship takeovers
About 15% to 20% of the ships leaving Africa never arrived in the Americas.[6] In thousands of cases the crews were overtaken by captured slaves, some of them warriors. Often the crew was killed and the Africans managed to sail back to Africa.[6] In other cases the ships were lost at sea.[6]
Some of the documented slave ship revolts are:
The Little George ship revolt happened after the ship Little George left Guinea in June of 1730. It was carrying 96 slaves to Rhode Island. Several of the African men slipped out of their shackles and overpowered the crew. They killed three of the crew who were on deck at the time. The rest were taken prisoner. The Africans sailed the ship back to the Sierra Leone River where they abandoned the ship and still imprisoned crew.[6]
In 1732 a ship out of Portsmouth, New Hampshire captained by John Major had just loaded hundreds of slaves and was leaving when about 50 Africans took over the ship. The crew was killed with guns, axes, swords and other weapons taken from the crew members.[6]

In 1747 an American ship with a captain named Beers was taken over by hundreds of captive Africans in West Africa. All but two of the crew were killed with their own weapons. There was no record of how many Africans died during the short battle.[6]
A 1764 ship incident. An unnamed ship from New London, Connecticut had just taken on a load of slaves in Senegal. That night, while the ship was still in port, the Africans freed themselves and, using clubs, killed the entire crew and captain. The Africans then disappeared back into Senegal.[6]
