The morale of the American prisoners was easily broken, and each one strove to look out for himself even at expense of his comrade's life.

In contrast, the Turks maintained military discipline and group solidarity.

This evidence would seem indicate that, while individual differences were insignificant, cultural differences did influence adjustment to the camp situation.
There are also grounds to believe that different value systems influenced the way in which contrasting cultures adjusted to slavery.

While the African made the adjustment successfully, the American Indian, when he was enslaved, did not.

The African's agricultural labor had contained many similarities to the work required on the plantation, but the Indian, accustomed to a migratory hunting existence, was totally unprepared for plantation slavery.
