 While figures are not available for Oslyabya, one Russian account after the battle said that the Borodinos were approximately 1,700 long tons (1,700 t) overweight as they were overloaded with coal and other supplies that were stored high in the ships, reducing their stability. Oslyabya's main armor belt was fully submerged with a full load, much less any additional coal and supplies, and thus the four-inch-thick upper armor was the only available protection for the ship's waterline.
