Portrayal of a naval battle scene. On the right, four ships from the Brazilian squadron, which attack the Fort of Curuzu. On the left, a fortification on the coast, a battery and soldiers, an officer on horseback, pointing towards the combat that is taking place on the right, and, beside this, the Paraguayan flag unfurled on a mast. In the background, on the left, the Fort of Curuzu, the roof of a house and tents. Near the bank, at the bottom and to the left, a rowing canoe with men inside. Light blue sky with clouds and smoke in cinque and black tones from the boats. Author's signature in the lower right corner: "E. De Martino".
