On the nineteenth, General Jackson issued an address from headquarters, from which we reproduce as follows: "The flag-vessel, which was sent to the enemy's fleet at Mobile, has returned, and brings with it intelligence, extracted from a London paper, that on the twenty-fourth of December articles of peace were signed by the commissioners of the two nations." Thus, on the day after the first landing of the British army on Louisiana soil, and after the first battle was fought at night, terms of peace were agreed on. It was fifteen days after that auspicious event until the battles on the eighth occurred, causing such disaster and loss of valuable lives to the English army and nation; and fifty-two days from the signing of articles until a message of the good news was received by the commander-in-chief of the British forces. There was no alternative but to await the slow passage of the ship across the wide Atlantic, with sails set to breeze and calm, and sometimes tossed and delayed by adverse storm. To-day, the news of such an event would be flashed over the great cables under the sea and the network of electric wires throughout the land, in the twinkling of an eye after its occurrence. Such an advantage at the time would have been worth to England the entire cost of the telegraph system of the world. LEGISLATURE SUPPRESSED UNDER MARTIAL LAW--CHARGES OF TREASONABLE UTTERANCES. On the morning of the twenty-eighth of December, just as the British began their attack on the American line, General Jackson issued an order forcibly forbidding the meeting of the Legislature in session, and for taking possession of the legislative halls. The proceeding created great excitement in the civil and military circles of the city, especially among the members of the body and their immediate friends. The author is indebted to Mr. William Beer, of the Howard Library of New Orleans, for the loan of a copy of a rare little book entitled "Report of the Committee of Inquiry on the Military Measures Employed Against the Legislature of the State of Louisiana, the 28th of December, 1814." In the full report of the testimony taken by the committee, we have a history of the causes which led to this open rupture between the commander-in-chief and the General Assembly of Louisiana, and of its incidents and issues.
