The site is not a cemetery as what normally comes to mind with individual graves, it is a mass grave.

On the morning of Sunday, March 26, 1676 during King Philip's War, Captain Michael Pierce led 63 English colonists and about 20 Wampanoag loyal to the settlers toward Cumberland in pursuit of Narragansett Indians who had been raiding the area. Pierce's troops caught up with but were ambushed and nearly all killed in battle, the battle was one of the biggest defeats of colonial troops during King Philip's War. The Narragansett lost only a handful of warriors.
Nine of the colonists who were taken prisoner and likely tortured to death by the Narragansett. The nine dead colonists were buried in a mass grave by English soldiers who found the corpses and buried them the next day. The soldiers created a pile of stones to memorialize the colonists. This pile is believed to be the oldest veterans' memorial in the United States, and a cairn of stones has continuously marked the site since 1676.
The cairn of stones was cemented into a solid memorial by the Trappist monks that at one time occupied the property. In 1928 the State of Rhode Island added a plaque: "On this spot, where they were slain by the Indians, were buried the nine soldiers captured in Pierce's Fight, March 26, 1676."
The site is located on the grounds of the former Trappist monastery of Our Lady of the Valley, now the Cumberland public library, and is an approximately 15 minute walk behind the main building on a rise in the woods.

Directions:

Follow the road to the right past the main building, you will come to a low white building on your left and at that point should see a break in the chain link fence that is on your right. There is a low metal guardrail in the break, step over and you should be on a walking path. Turn right and not far up the path will divid, take the left path, it will bring you through a field. In the field, it again branches out – take the left again and keep walking out of the field through the trees. From leaving the field to reaching the monument is about the same distance that you walked to get out of the field from the start. Coming down over a small rise, there is a path to the right that brings you to the elevated area that the monument occupies – you can see the monument from the rise when on the path.
