It will be noticed that Von Hoist, not having access to Polk's diary, worked in the dark in regard to the President's Mexican policy and attributes designs to him which he did not entertain. The New York Sun asserted in October that it had advocated the occupation of Mexico in May. Niles's Register, LXXIII, 113.
