September 20

September 20 is a decisive date in the machinery of Cardinal Richelieu’s plot against Queen Anne of Austria. On that day, Richelieu tells Louis XIII that the municipal fête will take place on October 3, a choice designed to appear natural while allowing time for Milady the English spy to return from London. The date thus joins calendar, intelligence, court ceremony, and political surveillance: a seemingly ordinary appointment becomes the timetable for exposing the Queen’s secret dealings.

The Date Within the Court Plot

Richelieu’s calculation follows a letter bearing a London stamp. Milady reports that she possesses the Queen’s diamond studs but cannot leave London because she lacks money, and asks for five hundred pistoles; she expects to reach Paris four or five days after receiving the funds. Richelieu counts four or five days for the money to be sent and another four or five for her return, then adds two further days for contrary winds, accidents, and what he calls a woman’s weakness. His arithmetic produces a twelve-day margin, sufficient to place Milady’s arrival before the planned fête.

The date is therefore not merely a chronological marker. It is the point at which Richelieu turns uncertain information into a controlled schedule. The Queen’s possession of the diamonds is to be tested in public, while Milady’s movements are made to fit the same timetable. A letter, a financial remittance, a journey from London, and a royal entertainment become parts of one coordinated sequence.

October 3 and the Public Test

When Louis XIII asks whether the fête has been scheduled, Richelieu answers that October 3 will fall “wonderfully well,” because the King will not appear to have gone out of his way to please the Queen. The apparent courtesy is calculated concealment. The fête gives Louis XIII a public occasion to ask whether Queen Anne’s diamond studs become her, while Richelieu avoids openly revealing that the ceremony has been arranged to verify her possession of them.

September 20 consequently establishes the interval between private preparation and public examination. Richelieu also instructs Louis XIII to tell the Queen on the evening before the fête that he wishes to see how the diamond studs become her. The request is framed as an aesthetic compliment, but its practical purpose is evidentiary: the jewels are to display whether the Queen has obeyed the King and whether the suspected transfer to London can be exposed.

Time, Intelligence, and Political Control

The date illustrates how political power operates through timing as much as through force. Richelieu cannot simply accuse Queen Anne; he must arrange circumstances in which the desired proof will appear before the court. His control depends on synchronizing communications, money, weather, travel, and ceremony. The twelve-day calculation makes contingency itself part of the plan, allowing for delays while preserving the intended confrontation.

This method belongs to the wider world of the reign of Louis XIII, where the King’s authority, the cardinal’s political power, military rivalry, and private loyalties constantly overlap. Elsewhere, the King insists that an edict forbids fighting, yet quietly receives the four men who have defeated the cardinal’s Guardsmen; he later rewards d'Artagnan with forty pistoles while maintaining the language of royal discipline. In the same fashion, September 20 records a court decision that is formally ordinary but secretly designed to serve a struggle between the King, the cardinal, Queen Anne, and the agents moving between them.

Contrast with the War Beyond the Court

The date also gains significance from the larger military context. The Siege of La Rochelle is presented as a political and military campaign aimed at destroying the last major Huguenot stronghold and closing its port to England. Buckingham’s landing on the Isle of Ré with ninety vessels and nearly twenty thousand men, followed by the English army’s worsening condition from poor provisions, illness, wrecked vessels, and rough seas, shows the scale of the conflict surrounding the court intrigue.

Yet the date’s importance lies in the contrast between those two kinds of warfare. At La Rochelle, hunger, naval access, fortifications, and battlefield losses determine events. In Paris, a date, a letter, five hundred pistoles, and a pair of diamond studs can carry comparable political force. September 20 belongs to the second theater: it is the quiet administrative moment in which a personal rivalry is converted into a public test and a private secret is placed under the pressure of ceremony.

Narrative and Thematic Significance

As a narrative device, September 20 creates suspense by making the future measurable. Richelieu’s calculation tells the reader that the Queen’s danger will not unfold indefinitely; it has been given a deadline, and every delay in Milady’s journey now matters. The date also exposes the difference between apparent time and operative time. The court sees a fête being scheduled, while Richelieu sees a twelve-day operation advancing toward proof.

The date’s deeper significance lies in its fusion of intimacy and statecraft. The suspected relationship between Queen Anne of Austria and George Villiers, Duke of Buckingham is treated as both a private attachment and a matter capable of aggravating relations between England and France. By fixing October 3 on September 20, Richelieu gives that private danger a ceremonial stage. The calendar becomes an instrument of surveillance, and the royal fête becomes the point at which affection, political rivalry, and material evidence are expected to collide.
