Question: During the American Civil War, which companies of the 69th Pennsylvania Infantry wore uniforms modeled after French Army regiments?
Context: The 125th Pennsylvania Infantry volunteered during the American Civil War and served a 9-month term from August 1862 to May 1863.  It selected the motto In God We Trust.  The Regiment fought at the Battle of Antietam under the leadership of Colonel Jacob C. Higgins less than six weeks after being recruited in Blair, Cambria and Huntingdon Counties.  The Regiment was noted for its charge through the East Woods, along the Great Cornfield, down Smoketown Road, past the Dunker Church, and into the West Woods.  While in formation beyond the Dunker Church in an 'overextended' position, the Regiment repulsed four counterattacks at a price of 229 casualties (33% of engaged) within 20 minutes.  A fifth, heavily reinforced Confederate counterattack forced a retreat with a desperate struggle to retain the Regimental colors.  Two weeks before the end of their enlistment, the 125th Pennsylvania also occupied the perimeter of Chancellorsville, Virginia, during the Battle of Chancellorsville. The Zouaves (] ) were a class of light infantry regiments of the French Army serving between 1830 and 1962 and linked to French North Africa, as well as some units of other countries modelled upon them.  The zouaves, along with the indigenous "Tirailleurs Algeriens", were among the most decorated units of the French Army. Jacob C. Higgins (1826–1893) was a native commander of Pennsylvania troops who participated in both major military conflicts of his time, the Mexican-American War and the American Civil War.  Among his Civil War commands, he guided the 125th Pennsylvania Infantry regiment under heavy fire during the 'Bloodiest Day in American History' at the Battle of Antietam and likewise during the 'Second Bloodiest Day of the Civil War,' May 3, 1863, at the Battle of Chancellorsville.  Following the muster out and return home of the 125th PA, the Gettysburg Campaign sent cavalry under Confederate General John D. Imboden to threaten vital railroad resources at Altoona and iron production facilities in the Juniata River watershed; in response, Emergency Militia was organized by Colonel Higgins and minimized this northwestern incursion. The 69th Pennsylvania Infantry (originally raised as the 2nd California) was a volunteer regiment in the Union army during the American Civil War.  Part of the famed Philadelphia Brigade, it played a key role defending against Pickett's Charge during the Battle of Gettysburg.  Companies I and K, designated as the regiment's skirmisher companies, wore a very Americanized Zouave uniform.  This uniform consisted of a dark blue Zouave jacket with green trimming, green cuffs, and sixteen brass buttons down the front on both sides of the jacket, a sky blue Zouave vest, chasseur sky-blue trousers, and a dark blue kepi.  This was one of the few Zouave uniforms that did not use red as the jacket trimming.  However, the Zouave uniforms were mostly destroyed during the Peninsula Campaign and were not replaced. Samuel Morton Zulick (March 1, 1824 - June 10, 1876) was an American Civil War officer and medical doctor who was promoted to brevet brigadier general of volunteers on March 13, 1865 for "bravery and efficiency as an officer".  On May 15, 1861, he enlisted as private with the 29th Pennsylvania Volunteer Infantry.  He was promoted to captain three months later.  He was later promoted to major after the Battle of Antietam and to lieutenant colonel after the Battle of Chancellorsville.  He later served at the Battle of Gettysburg and marched with Sherman to Savannah.  His father was a native of Frankfurt am Main while his mother was a native of Philadelphia.  His son, Philip S. Zulick, served in the 45th Pennsylvania Infantry. Marie Tepe (1834–1901), known as "French Mary," was a French-born vivandière who fought for the Union army during the American Civil War.  Tepe served with the 27th and 114th Pennsylvania Infantry Regiments. The 90th Pennsylvania Volunteer Infantry was a volunteer infantry regiment which served in the Union Army during the American Civil War.  They wore a chasseur uniform.  The uniform consisted of a dark blue habit veste with white trimming, baggy sky blue trousers, and a dark blue kepi.  The buttons on the habit veste was unique to the 90th Pennsylvania.  They were the only Union regiment in the entire war to have a specific button design. The Fort Mill Ridge Civil War Trenches are battle trenches originally dug between 1861 and 1862 and lined with chestnut logs by the Confederate artillery during the American Civil War to defend the approaches to Romney on the Northwestern Turnpike and the South Branch Potomac River.  The trenches were then refurbished between March and June 1863 by the 54th Pennsylvania Infantry and the 1st West Virginia Infantry.  When Colonel Jacob M. Campbell (54th PVI) garrisoned Union forces at Romney, camps were set up at nearby at Mechanicsburg Gap. The following is a list of Union Army regiments from the District of Columbia during the American Civil War.  A total of 15,131 men fought in two regiments and four battalions of infantry and one regiment of cavalry.  Other independent companies were raised during the war for local defense, including 33 companies of infantry and one company of cavalry raised from the District militia from April to July 1861. The 114th Pennsylvania Volunteer Infantry Regiment was an infantry regiment that served in the Union Army during the American Civil War.  They were notable for their colorful Americanized version of the Zouave uniform worn in emulation of certain French light-infantry units that became world-famous during France's colonization of North Africa, the Crimean War, and the Second War of Italian Independence fought in the years prior to the American Civil War.  The regiment was the brain-child of Charles H. T. Collis, an Irish immigrant who settled in Philadelphia becoming a prominent young lawyer.  Collis initially raised only a small company of men calling them the "Zouaves d'Afrique" which served while attached to other regiments.  They saw action in the 1862 Shenandoah Valley Campaign, the Battle of Cedar Mountain, and the Battle of Antietam.  The "Zouaves d'Afrique" were much admired for their military bearing and prowess in battle to the point that it was decided to raise a full-sized regiment which was given the numeric designation of 114th Volunteer Infantry.
Answer: Companies I and K, designated as the regiment's skirmisher companies, wore a very Americanized Zouave uniform.
