My scheme of defence consisted in blocking up all the door and window openings throughout the building with a good substantial wall of sand-bags, leaving here and there small loopholes just wide enough to admit of a musket being pointed through them.  My musketrymen would be stationed at these loopholes, each man having an assistant who would stand by to pass him a fresh cartridge and bullet as soon as his weapon was discharged; and of course the musketrymen and their assistants would be moved from room to room as required, according to the point against which the attack was most strongly directed.  I considered that we ought to stand a very good chance of making an effective defence, because it would be exceedingly difficult for our assailants to force a way into the building so long as our sand-bag walls stood firmly, and I believed it would require more courage than a negro possessed to charge home to them and overthrow them in the face of such a fire as we could direct upon them from the advantageous position which we should occupy. Moreover, we should possess the important advantage of being almost completely protected from their fire, and consequently should be able to take aim coolly and collectedly, while they would be fully exposed, there being no better cover for them than a few scattered bushes here and there, which I determined to remove, should there be time after our more important defences were complete.
