“Government sends you a commission as colonel of the mounted grenadiers, and hopes that by the continuance of your steadiness and zeal you may present the country with a corps capable alone of securing the liberties of your fellow-citizens.”

Meantime San Martin had married Doña Maria de los Remedios Escalada, a beautiful girl of one of the first families of the city.

San Martin made no pretence of being a politician, but among friends he spoke plainly his opinions:—

“Until now the United Provinces have fought for no one knows what, without a flag, and without any avowed principles to explain the origin and tendency of the insurrection. We must declare ourselves independent if we wish to be known and respected.”

With these ideas he did not hesitate to join those who desired the convocation of a Constituent Congress, but he saw the necessity of establishing some powerful nucleus of political force which should bring superior intelligence to influence popular movements, preparing among a few that which should be the apparent will of all. This idea he, aided by Alvear, carried into effect by the installation of the celebrated secret society known as The Lautaro Lodge, which exercised so great and so mysterious an influence upon the destinies of the revolution.

This Lodge was established in Buenos Ayres about the middle of the year 1812. Its members were of all political parties, but the majority were of the party at that time dominant in the State. The society was organised in various grades; in the first, neophytes were initiated according to the ritual of the Masonic lodges which were introduced into Buenos Ayres prior to the outbreak of the revolution; in the higher grades they were initiated into the higher purposes of the society, and behind these was hidden the central lodge (Logia Matriz), in which lay the supreme power of the society.

The declared object of the Lodge was:—

“To work systematically for the independence and happiness of America, proceeding with honour and justice.”

Thus membership was exclusively confined to men of American birth. By its constitution, if any of the brotherhood was elected supreme ruler of the State, he could take no important step without consulting the Lodge; he could not appoint a diplomatic agent, general-in-chief, governor of a province, judge of an upper court, high church dignitary, nor general officers, and could not punish any member of the brotherhood, by his own authority. It was a law of the Society that all members should mutually assist each other in all the exigencies of civil life; that at the risk of life they should uphold the decrees of the Lodge; and should inform it of anything which could influence public opinion, or affect the public security. To reveal the secret of the existence of the Lodge “by word or by sign” was punishable by death by such means “as might be found convenient.” This penalty, was, however, only intended to have a moral effect. By an addition to the constitution, it was arranged that when any brother of the Logia Matriz was named general of an army or governor of a province, he should have power to establish an affiliated society, with a smaller number of members.

The Society failed to secure the adhesion of the members of the then Government, but most of the popular leaders joined the Lodge, and its ramifications soon extended to all classes, the most notable adherent being Dr. Don Bernardo Monteagudo, who had great influence among the younger citizens.
