The Ninth Regiment was created on June 11, 1861 under the command of Colonel Cass in Boston, recruiting primarily Irish-Americans.
Initial funding for the regiment came from Patrick Donahoe, publisher of the Boston Pilot. Initially bivouacked at Boston's Faneuil Hall, they later camped at Long Island in Boston Harbor.
On June 30, 1861, the unit arrived in the Washington, D. Vicinity and was welcomed by President Abraham Lincoln. They remained in the vicinity of Arlington, Virginia performing picket duty and built a fort on the Potomac River named Fort Cass after their commanding officer. As a unit of the Army of the Potomac under the command of Major General George B. McClellan, the Ninth Regiment moved south with the rest of the Army in pursuit of Confederate forces.On June 26, 1862 the Ninth Regiment participated in the Battle of Mechanicsville, about six miles from Richmond Virginia, which resulted in a Union Army victory and more than 2,000 Confederate casualties. The next day, the regiment was assigned to hold the bridge over the mill creek in the action that later became known as the Battle of Gaines Mill. The regiment was ordered to hold the bridge pending the arrival of two supporting regiments.
The support troops were delayed in their arrival, and the Ninth Regiment successfully repelled several Confederate assaults on the bridge. The supporting troops eventually arrived, but by this point the opposing forces had built their strength and the Ninth was unable to hold the bridge any longer. Eventually, Confederate forces led by General James Longstreet and General Ambrose Powell Hill, broke the Union line, forcing the Union Army into retreat. The Ninth Regiment brought up the rear of the retreat, fighting a rearguard action against the opposing forces.
The Union Army lost 6,000 killed or wounded in this battle and the Ninth Regiments casualties totaled 252 men. The Ninth Regiment participated in the Battle of Malvern Hill on July 1, 1862 as part of the Peninsular Campaign waged by the Union Army intending to capture the city of Richmond, Virginia. The Ninth Regiment held the hill and prepared it to withstand a siege by the Confederate Army.
Supported by five Union gunboats on the nearby James River, and benefiting from favorable geography and extensive defensive preparations, the Union Army withstood repeated charges and inflicted heavy casualties on the Southern forces. It was in this battle that Colonel Cass received the mortal wound in his face and mouth that eventually took his life. When Colonel Cass fell in battle, command of the Ninth Regiment was assumed by Acting Lieutenant Colonel Hawley and Cass was removed from the field.Colonel Hawley was subsequently wounded in the same action, and command fell to Acting Major, Captain OLeary. The units casualties were very heavy; along with losing their two top commanders, roughly half the regiment was put out of action, totaling 166 men. The Ninth Regiment was assigned a camp-ground at Harrison's Landing, and on 4 July 1862, General McClellan reviewed the army.
On 8 July 1862, President Lincoln made a visit to the camps, and reviewed the army by moonlight. He died in Boston, July 12, and his funeral was attended by Lieutenant-Colonel Guiney, Major Hanley, and other men of the Ninth who were home on sick leave. About this time, the men of the Ninth Regiment heard of his death.Colonel Cass was buried with military honors at Mount Auburn cemetery, and his widow and children were the chief mourners. His military awards were the purple heart, and the medal of honor. Statue of Thomas Cass in the Boston Public Garden. Some years after Col Cass' death, a memorial statue of him was placed in the Boston Public Garden.

Brooks received a gold medal for the statue underscoring the improvement on the original.This statue may be seen today on the south walk of the Public Garden.
