I came across this image again today while studying naval terms and marine art:
It's a painting by the famous Impressionist painter Edouard Manet (1832-1883) entitled
"The Battle of the Kearsarge and the Alabama."
It depicts the single-ship action between the USS Kearsarge and the CSS Alabama in The Battle of Cherbourg off the coast of France in 1864.
Though Manet himself didn't witness the battle, he almost certainly drew from first-hand accounts of other French citizens, hundreds of whom witnessed the battle as it unfolded just outside the Cherbourg harbor.
I find it a powerful composition and a good example of marine art and historical illustration.
