Excavations at a field hospital linked to the Battle of Waterloo have uncovered amputated leg bones and a dense scatter of musket balls, offering rare physical evidence of the desperate surgery and close-quarters fighting that took place while the battle raged on 18 June 1815.

Until now, only one complete skeleton—that of Private Friedrich Brandt, a German soldier—had been recovered from the Waterloo battlefield in modern-day Belgium. Most of the estimated 7,000 Prussian, 15,000 Seventh Coalition, and 25,000 French casualties were either buried in mass graves or left to decompose where they fell. Horses met the same fate, abandoned on the open field. The latest finds from the Mont-Saint-Jean farm change that sparse record.

Archaeologists working with the Waterloo Uncovered project located the remains of a field hospital in the farm’s former orchard. There they recovered several lower leg bones that show clear evidence of crude wartime amputation. One limb appears to have suffered a catastrophic wound; another bears the unmistakable marks of a surgeon’s bone saw, cuts almost certainly made while the battle was still under way. The bones are believed to have belonged to Allied soldiers.
Contemporary estimates suggest that as many as 6,000 men were treated at the Mont-Saint-Jean Field Hospital. Care was primitive: the primary goal was to keep the patient alive, not to save the limb. Roughly 65 percent of wounds at Waterloo struck the arms or legs, inflicted by cannonballs, musket balls, sabres or lances. Amputation without anaesthetic was a standard, if brutal, response.

The same trenches that yielded the bones also produced a startling concentration of projectiles. In a single half-day of digging the team recovered 58 musket balls fired by both sides. Professor Tony Pollard, lead academic on the project, described the discovery as evidence of “a previously unknown action at the very doors of the Mont St. Jean Field Hospital.” The farm lies approximately 1,900 feet behind the main Allied line. Pollard and his colleagues interpret the dense scatter as the residue of a French cavalry charge that swept down the slope into the hospital grounds, only to be met by determined defensive fire.

Additional artefacts reinforce the picture of intense combat in an unexpected location: numerous coins and buttons belonging to soldiers, and a six-pound cast-iron cannonball. Together the finds supply the most direct material evidence of the battle recovered in recent years.
The excavation team itself includes veterans and serving military personnel alongside professional archaeologists. Pollard noted that the sudden appearance of human remains “immediately changes the atmosphere on a dig,” creating “a very poignant connection with the people who suffered here in 1815.” For some participants the work has proved therapeutic. Mike Greenwood, a team member, observed that archaeology conducted among fellow service personnel offers a supportive setting, places individual experience in a wider historical context, and provides a practical, almost meditative process that can ease the burdens of post-traumatic stress.
Three additional leg bones, dozens of musket balls, coins, buttons and a cannonball have now been added to the sparse physical record of Waterloo. The discoveries do not merely illustrate the scale of the slaughter; they locate a previously undocumented firefight at the threshold of a field hospital and document, in bone and metal, the grim medical realities of the day. The Waterloo Uncovered project continues its work, and further finds are expected to refine—and in places rewrite—what is known about one of history’s most famous battles.
