I am looking for some advice on some thing I am working on. When the First Michigan Three Month Volunteer Infantry Regiment left for war they were armed with whatever available weapons the Michigan Militia had at the time. Michigan only had had 1226 percussion muskets and 330 Hall rifles. I would like to say they were reasonable well armed, but not sure this is true. The pre War militia companies who were included in the First Michigan Thee Month Infantry brought with them 328 rifled muskets (some of which were referred to as improved percussing rifled muskets). Most of the other Michigan pre war militia companies went into the 2nd, 3rd and 4th Michigan Infantry Regiments. Pre war they also held the best of what long arms Michigan had (372 rifled muskets, some being improved percussion rifled muskets). Some of these companies may have had their rifled muskets taken away to arm the First Michigan Three Month Volunteer Infantry Regiment. This means that the First Michigan Three Month Volunteer Infantry Regiment might have had 700 rifled muskets (perhaps 100-300 of these being improved percussion rifled muskets) and the rest possibly being older rifled muskets, smooth bore muskets, or Hall rifles. If the above is true, at the First Battle of Bull Run, could I say First Michigan Three Month Volunteer Infantry Regiment were reasonably well armed? Although most Michaign's records were destroyed in a fire I have pieced together the following information: Starting in 1850 Michigan begin sending flintlocks to the Watervliet and Alleghany arsenals to be converted to percussion. It would appear some or most of these were part of a shipment of 260 bright 1st class model 1822 muskets which arrived on 22 August 1846. On July 31 1844 160 muskets with accoutrements and 160 rifles with accoutrements arrived. The State received 330 percussion muskets and accoutrements on October 1 1850. In 1856 120 improved percussion muskets arrived.
