Smallpox is a symbol of the uncontrollable, devastating forces of fate that shape the lives of the characters. The disease sets the stage for the beginning of the novel, as this brutal agent destroyed several members of Elsbeth’s biological family before the novel began. The disease left her with permanent scars (both physical and emotional) that serve as a testament to her trauma and her resilience as a survivor. Throughout the siege of Boston, the threat of smallpox lingers. It is visually represented by the red flags on the doors of infected houses, which symbolize the ever-present possibility of death. The epidemic becomes intertwined with the political conflict, as George Washington gives “credit to it, as it has made its appearance on several of those who last came out of Boston” (43). This statement aligns the epidemic with the inhumanity of war.

The symbol’s meaning evolves as the narrative progresses. While it begins as a force of pure destruction, the town-wide inoculation transforms it into a catalyst for communal survival and found families. The shared experience of sickness and recovery solidifies the bonds within the Pike household, with Elsbeth’s role as a caregiver cementing her place in this new family structure. However, the disease never loses its deadly power. Hannah Sparhawk, having contracted the pox “in the common way” (329), suffers and dies, a tragic reminder of the disease’s lethality and the limits of human control. Ultimately, smallpox and the scars it leaves behind symbolize both the trauma inflicted by a merciless world and the strength required to survive within it, embodying the central tension between fate and resilience.

The motif of letters and communication is central to the novel’s exploration of truth, deception, and power. In a world of physical distance and political turmoil, written correspondence becomes a force capable of shaping reality and controlling destinies. This is most powerfully illustrated through Captain Hunter’s cruel manipulation of Hannah Sparhawk. He forges letters from her grandmother to maintain control over her inheritance and her life, effectively holding her captive through a web of lies. When Hannah questions the handwriting in one of these letters, Hunter dismisses her concerns, claiming, “Her hands tremble now, on account of her illnesses and age. She dictated that to the nurse” (136). This calculated deception isolates Hannah from her only remaining family, demonstrating how communication can be weaponized to exploit the powerless.

In contrast, letters also function as vessels of truth and hope, bridging the emotional and physical distances between characters. Elsbeth’s despair is fueled by the long silence from her father, making the arrival of his single letter from Halifax a pivotal moment. The letter resolves the mystery of his disappearance, revealing he was “attacked by a group of sailors who kidnapped me—pressed me into service for the King” (307). This revelation provides her with the emotional anchor needed to endure hardship. The motif emphasizes that survival in a world of crisis often depends on the ability to control narratives, whether through the perpetuation of life-altering lies or the discovery of life-affirming truths. Letters in the novel are never neutral; they are tools that either build prisons of deception or offer keys to freedom.
