USCH-07 Pioneer Corporal
Infantry Pioneers had much the same purpose as modrn combat engineers. On the march, they followed the advance guard and made quick repairs to bridges and roads. In attacks on fortified positions, they led the way to chop gaps in the enemy’s abbatis and palisades. During retreats, they marched with the rear guard, destroying bridges and obstructing roads. In camp, they improved the site and improvised roads. This demanding work required strong, reliable, and intelligent men. Scott’s pioneers proved so useful that the practice was extended to all infantry regiments in 1815 and continued in use through the Mexican war.
