Question

what is the 19th - century practice being depicted in this engraving?

Explanation:

This 19th-century practice saw British naval officers seize merchant sailors (often from neutral or enemy ships) to serve in the Royal Navy, a major source of tension between Britain and the United States leading up to the War of 1812. The image shows British personnel taking sailors from an American ship, matching the key details of impressment.

Answer:

The practice depicted is impressment (press-ganging), specifically the forced recruitment of sailors from one ship (here, an American vessel, indicated by the U.S. flag) into a British naval ship (indicated by the Union Jack).
