The Union Army had its famed 69th Regiment, all Irish. The South too had its Irish Brigade. The Sixth Louisiana Infantry Regiment was largely Irish. A key component of that Regiment was a company sized unit known as the Louisiana Tigers. They were commanded by the remarkable Maj. Roberdeau Wheat. Traveling from New Orleans to Virginia at the outset of the war, the Tigers and the Fourteenth Louisiana Regiment, mostly Irish, started a riot in Grand Junction, Tennessee. The commander had to shoot seven soldiers, killing them and wounding another nineteen to stop the riot.
But, in the heat of the action, the Irish always distinguished themselves. Gen. Richard Taylor commanded the Sixth Regiment for some time during the Shenandoah campaign under Stonewall Jackson. Taylor was a former Know-Nothing. In Louisiana, the Know Nothings caused riots that killed a few Irish immigrants. At least initially, Gen. Taylor was skeptical about his Irish charges. But, during the Shenandoah campaign they performed exceedingly well. In that campaign, Gen. Jackson had to march his “foot cavalry” over dozens of miles over several days. The Irish always responded. Even today, Infantry would not be expected to march more than 12-15 miles in one day. During the Valley Campaign, they marched 20 miles in one day and 30 the next.
In May, 1862, the Louisiana Brigade, which included the 6th Regiment, made an exhausting march to Strasbourg, Virginia in the oppressive May heat. Union cavalry pressed them and caused them to panic. The Irish provided a rear guard, which helped restore order. Retreat is one of the most complicated military maneuvers. Even the most experienced units can collapse. But, the Irish then refused to be relieved throughout the night, insisting they would protect the rear. The weather poured that night, dropping hail the size of “hen’s eggs.” Occasional artillery fire would not dissuade them from their duty. They cried out, “We are the boys to see it out!” This loud assurance “from half a hundred Tipperary throats”prompted Gen. Taylor, the former Know-Nothing, to comment years later that ever since, his heart “warmed to an Irishman since that night.”
