The formal declaration of war between the Vicomte de Valmont and the Marquise de Merteuil occurs in a pair of letters dated December 4. Valmont demands that Merteuil choose between renewed intimacy and enmity; she answers on the same sheet that she accepts war. The exchange makes a private rupture unmistakable: two former lovers and allies, each aware of the other’s power, turn their capacity for mutual destruction into an open threat.

Background and Stakes

Valmont frames the dispute around what both already know: each has enough in hand to ruin the other, and each therefore has reason to exercise restraint. He does not present their options as simply reconciliation or destruction. There are, he insists, many possible arrangements between the two extremes. Yet he narrows the immediate question to a choice that cannot be postponed: from that day, he will be either Merteuil’s lover or her enemy. The pressure comes not from a lack of alternatives in principle but from his refusal to let their relationship remain undefined.

That demand draws force from their history. Valmont speaks of restoring their former liaison and of becoming more closely united again, presenting intimacy as a possible return to their earlier partnership. Their correspondence elsewhere shows the practical basis of that alliance: Merteuil has invited Valmont to help turn Cécile’s prospective marriage to the Comte de Gercourt into a source of humiliation for him. Their connection has involved more than private affection; it has also offered a channel for schemes and mutual assistance. The ultimatum therefore places both dimensions at risk, without specifying which past grievance has finally made the old arrangement untenable.

The stakes are sharpened by the balance Valmont acknowledges. Neither writes as though the other were powerless or easily dismissed. Their shared capacity to cause harm makes restraint a rational interest, but it also means that a refusal can be interpreted as a serious escalation. Valmont’s proposal is thus both an appeal to renew the bond and a warning that he will use the conflict between them if she declines.

Valmont’s Ultimatum

Valmont says that Merteuil would prefer to delay a decision, and he explicitly refuses to let her remain in uncertainty. He argues that leaving her room to evade a clear answer would expose him to being played. The demand is designed to close off the kinds of maneuver he expects from her: he says that neither her reasoning, whether sound or unsound, nor any endearments used to disguise a refusal will persuade him to accept ambiguity.

At the same time, his letter declares a preference for peace and renewed union. That preference is not unconditional. Valmont says he believes he has both the right and the means to break their peace if necessary. He then defines the threshold: the slightest obstacle from Merteuil will count, on his side, as a genuine declaration of war. His two-word answer requirement makes the ultimatum sound almost simple, but the simplicity is coercive. It leaves her a choice while also announcing in advance how he will interpret resistance.

The letter’s form helps stage this turn. Valmont addresses Merteuil directly, anticipates her attempts to evade or soften a refusal, and converts the reply into an immediate test of allegiance. His language moves from a claim of mutual self-interest to a personal demand, then from a stated wish for peace to a threat of conflict. The movement is decisive: the possibility of reconciliation remains present, but only on terms he sets and only if Merteuil answers without delay.

Merteuil’s Answer

Merteuil writes her response at the foot of Valmont’s letter rather than sending a separately introduced argument. Her brief answer accepts the war he has defined. In that placement, the reply is materially joined to the ultimatum: the demand and its refusal of reconciliation occupy the same page, with no intervening negotiation recorded in this exchange.

Her answer does not explain her reasons, dispute Valmont’s account of their choices, or offer another arrangement. The brevity leaves those matters unstated. What it does establish is that she will not accept his proposal of renewed intimacy on the terms presented. Valmont’s prediction that an obstacle will constitute war becomes effective because Merteuil meets the condition with an unequivocal answer. The exchange therefore records not merely a threatened conflict but its formal acceptance by both parties.

Consequences and Significance

The declaration changes the meaning of their relationship from a potentially recoverable alliance into open antagonism. Their former intimacy has not erased their knowledge of one another; instead, Valmont identifies that knowledge as a source of danger for each. The same shared history that once supported conspiracy now makes the prospect of betrayal especially consequential. Yet this exchange does not disclose the particulars of what either can reveal or do, nor does it narrate a retaliatory act. Its immediate consequence is the explicit break in terms, not a completed campaign of revenge.

The scene also makes correspondence an instrument of action. Valmont uses a letter to set conditions, announce how he will interpret a refusal, and threaten the consequences; Merteuil uses the space beneath it to accept the conflict. The letters do not simply report a rupture after it has happened. They enact it. The declaration is therefore a turning point in their connection: mutual caution gives way to an adversarial pact, and the possibility of peace is made contingent on submission to a choice that Merteuil rejects.
