What was robert lindeuxs purpose in painting the trail of tears? what evidence in the painting suggests his purpose?

This picture, The Trail of Tears, was painted by Robert Lindneux in 1942. It commemorates the suffering of the Cherokee people under forced removal. If any depictions of the "Trail of Tears" were created at the time of the march, they have not survived.
