 The assassins then turned their attention to the Prince Royal, Luís Filipe, who had stood to draw and fire a hidden revolver but was hit in the chest.The bullet (from a small-caliber revolver) did not exit his sternum nor was it fatal; the prince reportedly fired four quick shots at his attacker, who fell from the carriage step.However, when Luís Filipe stood up he became more visible to the attacker with the rifle; the prince was struck by a large-caliber shot which exited from the top of his skull.
