Edgar Allan Poe [SEP] Military career
In September of that year Poe received “the very first words of encouragement I ever remember to have heard” in a review of his poetry by influential critic John Neal, prompting Poe to dedicate one of the poems to Neal in his second book "Al Aaraaf, Tamerlane and Minor Poems", published in Baltimore in 1829. Poe traveled to West Point and matriculated as a cadet on July 1, 1830. In October 1830, Allan married his second wife Louisa Patterson. The marriage and bitter quarrels with Poe over the children born to Allan out of extramarital affairs led to the foster father finally disowning Poe.
