This question will bring a subjective answer inasmuch the variables of the word "major" and "early stages" can be a point of debate.
The first major victory of the US Civil War by the North was the fall of New Orleans.
The reasons why this is considered major are the following:
New Orleans was the sixth largest city in the United States in 1862;
A. It was the commercial center of the "Deep South";
B. It had the nation's largest slave market;
C. Over one half of the nation's cotton came through the port of New Orleans;
D. The Confederates had the city well fortified and the fighting was intense; and
E. The overall value of taking this city by the North was in calculable.
The City surrendered on April 28, 1862.

The Battle of Bunker Hill took place on June 17, 1775, during the early stages of the American Revolutionary War. It was primarily fought on Breed's Hill, near Boston, Massachusetts. Although the battle resulted in a tactical victory for the British, it demonstrated the colonists' determination and ability to stand up to British forces.
The Battle of Bunker Hill, fought on June 17, 1775, was technically a tactical victory for the British forces, who took control of the Charlestown Peninsula. However, the heavy losses they incurred—over 1,000 casualties compared to approximately 400 for the American forces—boosted American morale and demonstrated that colonial fighters could stand up to the British army. The battle is often seen as a symbolic victory for the American cause in the early stages of the Revolutionary War.
The Battle of Shiloh, fought from April 6 to April 7, 1862, ended in a costly Union victory. Despite initial Confederate success on the first day, Union forces, reinforced by General Buell's troops, regrouped and launched a counterattack, forcing the Confederates to retreat. The battle resulted in significant casualties, with around 23,000 soldiers killed, wounded, or missing, making it one of the bloodiest battles in the early stages of the American Civil War. This victory bolstered Union morale and solidified their control over western Tennessee.
The head of Confederate forces at the Battle of Shiloh was General Albert Sidney Johnston. He commanded the Confederate Army of the Mississippi during the battle, which took place on April 6-7, 1862. Johnston was a key figure in the early stages of the Civil War but was mortally wounded during the conflict, leading to the eventual retreat of Confederate forces. His death marked a significant turning point in the battle.

The Battle of Antietam was not a clear victory for neither the Confederate nor the Union armies.
Antietam was the first major battle during the Civil War that actually turned the South away from attacking the North. Very few Southern forays into the North occurred after Antietam. The last, Gettysburg, ended in disaster for the South.
William was stronger.
