In Schindler's List what was manufactured in the factories and who were they for?

In "Schindler's List," the factories operated by Oskar Schindler primarily manufactured enamelware and munitions. These products were intended for the German military during World War II. Schindler's efforts to keep his Jewish workers employed in these factories ultimately saved them from deportation to concentration camps. His factories became a refuge, allowing him to protect over a thousand Jewish lives.
