General Jean-Baptiste Kl?ber and Egyptian Family (Sketches for "The Battle of the Pyramids") , c. 1835. In 1810, Gros exhibited a massive painting of Napoleon at the 1798 Battle of the Pyramids, one of the rare French triumphs in the failed campaign to conquer Egypt (1789-1801). After Napoleon first fell from power in 1814, the painting went into storage, until the new king Louis-Philippe chose to resurrect it for a history museum in Paris. However, perhaps to diminish Napoleon's significance, the government asked Gros to amplify the original with an addition at each end. This painting incorporates General Kl?ber, a famously successful military leader who had been excluded from the original painting.
