Being of opinion that, for the general defence of our country, we ought not to rely upon fortifications, but on men and steel; and that works calculated for resisting batteries of cannon are necessary only for our principal seaports, I cannot conceive it useful or expedient to construct expensive works for our interior military posts, especially such as are intended merely to hold the Indians in check. I have therefore directed stockade works aided by block-houses to be erected at Vincennes, at Chikago, at or near the mouth of the Miami of the lakes, and at Kaskaskia, in conformity with the sketch herewith enclosed, each calculated for a full company; the block-houses to be constructed of timber slightly hewed, and of the most durable kind to be obtained at the respective places; the magazines for powder to be of brick, of a conic figure, each capable of receiving from fifty to one hundred barrels of powder. Establishments of the kind here proposed will, I presume, be necessary for each of the military posts in Upper and Lower Louisiana, New Orleans and its immediate dependencies excepted. I will thank you to examine the enclosed sketch, and to give me your opinion on the dimensions and other proposed arrangements You will observe the block-houses are to be so placed as to scour from the upper and lower stories the whole of the lines. The back part of the barracks are to have port-holes which can be opened when necessary for the use of musketry for annoying an enemy. It will, I presume, be proper ultimately to extend palisades round the block-houses. * * * * * Statement compiled from the Records of the Adjutant General's office in the case of Fort Dearborn, with copies of orders: Fort Dearborn, situated at Chicago, Ill., within a few yards of Lake Michigan.
