Here is my information about the 1819 voyage of the French ship Le Rodeur:
Achieved using www.slavevoyages.com

Here is an account from the vessel demonstrating the resistance of the enslaved:
From There is a River by Vincent Harding

I found some discrepancies with the information on the account of Le Rodeur:
- This account comes from a primary source speech by M. Benjamin Constant, in the French Chamber of Deputies, on June 17th, 1820
- This account comes from A Practical Treatise on the Diseases of the Eye by William Mackenzie, 1830
