Context paragraphs:
Siege of Bastogne: The Siege of Bastogne was an engagement in December 1944 between American and German forces at the Belgian town of Bastogne, as part of the larger Battle of the Bulge.  The goal of the German offensive was the harbour at Antwerp.  In order to reach it before the Allies could regroup and bring their superior air power to bear, German mechanized forces had to seize the roadways through eastern Belgium.  Because all seven main roads in the densely wooded Ardennes highlands converged on Bastogne ("Bastnach" in German), just a few miles away from the border with neighbouring Luxembourg, control of its crossroads was vital to the German attack.  The siege was from 20 to 27 December, until the besieged American forces were relieved by elements of General George Patton's Third Army.

199th Infantry Regiment (United States): The 199th Infantry Regiment is a regiment of the United States Army, Louisiana Army National Guard.

The 199th Infantry Regiment was formed on 1 May 1952 and served the state of Louisiana until 4 August 1960, when it was consolidated with the 156th Infantry Regiment.  Between 1960 and 1997, the remnants of the 199th became known as the Louisiana Military Academy, and conducted training for the Guard.  The regiment was reactivated on 3 July 1997 as the 199th Regiment, in order to serve as the Louisiana National Guard's RTI.

It was established in 1923 from the old 2nd Hawaiian Infantry Regiment, and it served during World War II as part of the 24th Infantry Division.

The division was initially mixed, with two infantry regiments from the Grand Duchy of Baden, one infantry regiment from Prussian Saxony, and Prussian and Baden support units (cavalry, artillery, engineers, and service and support units).  While the infantry regiments and the divisional cavalry squadron were regular army units, the rest of the division was made up of reserve units and units formed during the war.  The 66th Magdeburg Infantry Regiment was taken from the 7th Infantry Division, and the 169th and 170th Infantry Regiments were taken from Baden's 29th Infantry Division.  The 52nd Infantry Division became more Baden as the war progressed, as the 66th Magdeburg Infantry Regiment, the regiment from Prussian Saxony, was replaced on April 6, 1917, by Baden's 111th Infantry Regiment "Margrave Ludwig Wilhelm".
