My dear Mr. Walker:
I have read your interesting book, "America Fallen." Under your reasonable supposition of a surprise invasion of our country without a previous declaration of war, the military operations you have outlined are perfectly feasible, and the outcome might easily be as disastrous to the United States as you have so graphically pictured.
I hope your work may be read so widely and seriously that its lessons, together with the evident lessons of the day, will result in the adoption of an intelligent policy looking toward national preparedness against war.
Sincerely yours,
Matthew E. Hanna.
