Perhaps I may at this point anticipate two questions which may possibly be asked: first, how was it that His Majesty's ships suffered such extensive damage and casualties; and second, why they were not able to silence the opposing batteries and fight their way through. In answer to the first, I would only say that warships are not designed to operate in rivers against massed artillery and infantry sheltered by reeds and mudbanks. The Communist forces appear to have been concentrated in considerable strength and are reported as being lavishly equipped with howitzers, medium artillery and field guns. The above facts also provide much of the answer to the second question, only I would add this. The Flag Officer's policy throughout was designed only to rescue H.M.S. "Amethyst" and to avoid unnecessary casualties. There was no question of a punitive expedition and His Majesty's ships fired only to silence the forces firing against them.
In 1949, Leontief used an early computer at Harvard and data from the U.S. Bureau of Labor Statistics to divide the U.S. economy into 500 sectors. Leontief modeled each sector with a linear equation based on the data and used the computer, the Harvard Mark II, to solve the system, one of the first significant uses of computers for mathematical modeling
