The Massacre of the Fort William Henry garrison is the attack on the British troops and civilians as they left the surrendered fort under agreed terms. It turns a formal capitulation into a catastrophe, exposes the limits of French control over its allies, and leaves the narrator with a lasting judgment on Montcalm’s failure to protect the departing column.

Surrender and Evacuation

Montcalm told the British that the fort could not be retained and would be destroyed, but promised that the garrison would receive the privileges due to soldiers. When Duncan Heyward asked about the British colors, Montcalm said they could be carried to England and shown to the king. Colonel Munro then signed a capitulation providing for the fort’s surrender in the morning, with the garrison retaining its arms, colors, baggage, and, in military terms, its honor. The narrator presents the agreement as a carefully defined promise, not an unconditional surrender.

At the evacuation, the French took possession of the gates and raised their flag over the fort. Nearly three thousand British men, women, and children moved across the plain toward the road through the woods. The French army stood assembled nearby and observed the departure, keeping the stipulated military honors and making no taunts. Many sick and wounded had to walk because the available vehicles and pack animals were occupied; the column’s orderly movement therefore carried a visible burden of exhaustion and vulnerability.

The Attack on the Column

As the column crossed the open ground, a dispute over a provincial soldier’s possessions drew Indigenous onlookers closer. The crowd then became alarmed when a Huron seized a woman’s shawl and took her child. The narrator describes the killing of the child and mother as the immediate crisis in the scene. Magua raised a whoop, and more than two thousand warriors emerged from the forest and attacked the departing people.

The soldiers tried to form solid ranks to deter the assault, but some lost their muskets in the confusion. The attack spread across the plain, while civilians and soldiers were trapped in the moving crowd or forced to flee. Alice saw her father, Colonel Munro, cross toward the French army to claim the escort promised in the capitulation. From above, Cora and Alice later witnessed the violence continuing as the French troops remained in place; the narrator says the attack subsided only when plunder displaced revenge as the assailants’ immediate purpose.

Causes and Political Context

The novel places the massacre within an unstable alliance rather than treating it as an isolated eruption. Magua had pledged not to act against the interests of the French king, but he had also declared that his hatchet would remain active until it was red with blood. Once the British had agreed to leave, he challenged the logic of continuing the war against them, yet the episode shows that such political reasoning did not secure their safety.

The Delawares’ position further reveals the strains within the French coalition. They had followed Montcalm into English territory and were encroaching on Mohawk hunting grounds, but withheld military support, citing the time needed to sharpen their hatchets. The narrator explains their reluctance as connected to an old treaty that had once made them dependent on the Six Nations for protection. Magua later used their alleged hospitality to British scouts as a diplomatic accusation: the Delawares’ villages, hunting grounds, women, children, and part of their fighting strength lay within French territory, leaving them vulnerable to suspicion from their allies.

Hawkeye describes white political maneuvering as having confused Indigenous alliances and turned related or neighboring peoples against one another. The narrative also connects this disruption to older grievances: white actions, the scout says, had helped turn brother against brother and bring the Mingo and Delaware onto the same path. These passages frame the massacre within colonial competition for territory and military allegiance, while making clear that the British evacuation agreement did not settle the conflicts shaping the region.

Consequences and Judgment

The narrator names the episode the Massacre of William Henry and treats it as a defining stain on Montcalm’s reputation. His courtesy, generosity, and military honor, evident in the surrender negotiations, are set against his failure to prevent the attack. The French troops’ presence at the plain, their earlier observance of the agreed honors, and their subsequent inaction sharpen the contrast between the promise of protection and the result. The narrator argues that political calculation overcame principle, and that Montcalm’s celebrated reputation may cause this failure to be forgotten.

The massacre also shadows the later pursuit of the Munro sisters and the rescue efforts led by Uncas. When Uncas gathered Delaware leaders, he appointed Hawkeye to command twenty men and offered Duncan Heyward an equal responsibility; Heyward declined the command and volunteered to serve beside the scout. More than two hundred Delaware warriors then marched out under Uncas’s direction. The episode thus remains active in the plot beyond the evacuation itself: it gives urgency to the rescue, while the novel’s wider account of divided Indigenous alliances links personal danger to the larger disorder of colonial warfare.
