Entering on the practice of law at Columbus, Ga., he continued there but one year, when he located in Mobile, in the year 1835. He soon received the appointment of United States attorney for the southern district of Alabama, but the death of his father occurring in Georgia, necessitated his return to that state, where he remained for twelve years, having taken charge of his father's estate and devoting his time to planting, the practice of law and the editorial management of the Columbus Times. It was during that period that he enlisted to serve in the Mexican war as the adjutant of the First Georgia Regiment. He returned to Mobile in 1853, entered the lumber business, was burnt out, and entered again the field of journalism by purchasing the Mobile Register. In 1856 he was appointed by President Pierce minister to Mexico, in which capacity he served for two years. Colonel Forsyth's mission to Mexico was attended by much labor and perplexity, as the duty was imposed on him of adjusting varied and numerous claims against the Mexican government, which claims originated in the nature of the war waged by the Mexicans. There were claims for imprisonments, murders, confiscation, and others, and while Colonel Forsyth labored without abatement, he had but timorous support from the Buchanan administration. As a matter of fact, President Buchanan was gravely absorbed in the rush of events which tended toward the approaching Civil War, which broke like a storm over the country in 1861, and his foreign policy was one of conciliation. The reason of this presidential policy concerning Mexico is now obvious. In view of the pending conflict in the American states, the hostility of Mexico, for any reason, would be serious. As an earnest advocate of the rights of the citizens of the American states at the Mexican capital, Colonel Forsyth was gravely embarrassed by the feeble support lent by his government, and this led to the severance of his relations with the diplomatic service. Having resigned, he returned to Mobile and resumed his editorial work. With qualifications so varied, he was frequently called into active service by the people. While his pen was actively employed, he was summoned to such important posts as that of mayor of Mobile, legislator, alderman in his adopted city, and other stations of public interest. In March, 1861, Colonel Forsyth was sent, together with Messrs. Crawford of Georgia, and Roman of Louisiana, on a peace commission to Washington. There was but slight hope of accomplishing anything, and it is doubtful if there was any more serious intention involved in the mission than that of gaining time for a more efficient equipment of the South for the pending struggle. It was a time for tactics, and a play for advantage. The mission was a bootless one, and in due time the war burst on the country.
