1835-1895
Born on a farm in Lansing, Tompkins County, New York, Wyckoff was 26 years old when the war broke out in 1861. He enlisted in the 32nd New York Volunteer Infantry Regiment (Company E / Company I).
During his two-year term of service (1861–1863):
Private to Officer: Wyckoff demonstrated strong leadership and reliability early on. He was promoted through the non-commissioned officer ranks before earning a commission as a Lieutenant and eventually reaching the rank of Captain.
Frontline Service: As Captain, he led his company through some of the VI Corps' most grueling engagements, including the Peninsula Campaign, Crampton’s Gap (where the 32nd NY suffered massive losses), Antietam, and Chancellorsville.
The 32nd New York Infantry Regiment (also nicknamed the "1st California Volunteers" because several early companies were recruited with ties to California) was a two-year volunteer unit.
Key Campaigns and Battles
1. First Bull Run (July 1861)
Shortly after arriving in Washington, the 32nd New York marched into northern Virginia under General Irvin McDowell.
2. The Peninsula Campaign & West Point (Spring/Summer 1862)
In the spring of 1862, the regiment was shipped to the Virginia Peninsula as part of General George McClellan’s campaign toward Richmond.
Battle of Eltham's Landing / West Point (May 7, 1862): This was the regiment’s first severe trial by fire. Landing by transports near West Point, Virginia, the 32nd New York was heavily engaged against General W.H.C. Whiting's Confederate troops while covering the Union landing. The regiment fought gallantly and drove the enemy back, though taking significant casualties.
Seven Days Battles (June 25 – July 1, 1862): The regiment saw heavy action at Gaines' Mill and fought through White Oak Swamp and Malvern Hill as the Union forces fought their way back to Harrison's Landing.
3. Maryland Campaign & Crampton’s Gap (September 1862)
The most severe combat in the regiment's history came during the Maryland Campaign:
Battle of Crampton’s Gap / South Mountain (September 14, 1862): Charged with assaulting a heavily defended mountain pass, the 32nd New York suffered devastating losses. Their commander, Colonel Roderick Matheson, and Major George Lemon were both mortally wounded. Lieutenant Colonel Francis E. Pinto had to take command of the combined remnants of the 32nd and 33rd New York Regiments.
Battle of Antietam (September 17, 1862): Just three days later, at the bloodiest single day in American history, the unit served in support positions under continuous artillery fire near the Sunken Road/Bloody Lane area.
4. Fredericksburg & Chancellorsville (Winter 1862 – Spring 1863)
Fredericksburg (December 1862): The regiment supported Union artillery and helped repel a Confederate attack on the New Jersey Brigade. They endured freezing conditions in open positions overnight.
The "Mud March" (January 1863): Participated in the infamous, rain-soaked, bogged-down march through thick Virginia clay.
Chancellorsville Campaign & Salem Church (May 1863): During General Joseph Hooker's campaign, the VI Corps crossed the Rappahannock and took Marye's Heights at Fredericksburg before advancing toward Salem Church, where the unit saw its final active skirmishing and rear-guard actions.
Regiment Summary & Muster Out
Muster Out: Because the 32nd New York was a 2-year regiment, its term of service expired in the spring of 1863. The regiment was officially mustered out in New York City on June 9, 1863.
Casualties: Over their two years of service, the 32nd New York lost 45 officers and enlisted men killed or mortally wounded in battle, and 54 men to disease.
Because William Ozmun Wyckoff rose from Private to Captain, he went through nearly every tier of the Army hierarchy:
Private -> Non-Commissioned Officer (Corporal/Sergeant): Promoted for reliability, skill, and survival through early trials.
NCO -> Lieutenant: Commissioned as a junior officer, often to fill vacancies left by casualties at West Point or Gaines' Mill.
Lieutenant -> Captain: Promoted to company command, likely following the high officer mortality rate during the Maryland Campaign (such as Crampton's Gap, where top leadership was lost).
As a Captain, he would have been responsible for commanding an entire company of ~80 to 100 men—leading them directly on the battle line, managing company rolls, rations, arms, and discipline.
Thank you to Gemini for providing information about the regiment and the campaigns William Ozmun Wyckoff participated in. It would have taken me much, much longer to bring together all this information.
