The part played by Nathan Mayer Rothschild (1777-1836) and his brothers in helping the British Government to finance military operations against Napoleon is legendary. Nathan's London House, N M Rothschild, dealt in bullion and foreign exchange, and his remarkable successes in these fields earned him the contract from the British Government to supply Wellington's troops with gold coin in 1814 and 1815, leading up to the Battle of Waterloo.
