Trying to find the exact number executed and who is not easy, but the New York Times of 1875 states it was about 20 Americans and 20 British citizens and did not give the number of Cubans. The cargo listed is a joke. Mostly about 200 bayonets and scabbards, 30 kilos of powder, 1 rifled cannon, 2 barrels of sand for casting, belts, uniform decorations, waterproof wire, cloth, rum and other misc items.
