It became clear that that someone has done a first rate job of building an on-line tool for 1812 Infantry Drill. The organization is the Ft. McHenry Guard. It has effectively recorded Infantry drill both using footplacement illustrations and frontal photos with drawings. To top it off, there are excellent details of handling the weapon properly. An Adobe® Flash module is necessary to see the video sequences that attend the images. Here's an opportunity for individuals looking for help, devoid of time or access to periodic drill sessions, to familiarize themselves with the essentials.
The sequences shown are as follows:

LESSON 1. Principles of Shouldered Arms
LESSON II. The Manual Exercise
LESSON III. On Loading
LESSON IV. On Firing

Click on the link below for information on Van Steuban's original manual which was still the backbone of the militia companies decades after the revolution. This is not in PDF form but can take you to abbreviated links with basic command instruction.
These will be the commands used in Kentucky Militia company formation.
We will endeavor to merge in with Smyths when in a "grand tactical" or brigade level operation. This link is produced by the NPS for use by their living history guides. If you scroll to the bottom, there is a small MPEG Movie (Windows Media Player needed) along with sequential visuals in the form of slides to accompany the basic load and firing commands.
