The Secret Siege was an eighteen-day standoff inside the Red Keep during the regency of Aegon III. It began as a campaign of arrests against the king’s household and the Hand, Thaddeus Rowan, former Hand, and became a test of who could claim to defend the king: the men controlling the wider castle, or the small group protecting him behind the gates of Maegor’s Holdfast. Viserys Targaryen’s defiance and Sandoq the Shadow’s defense kept the holdfast secure long enough for Aegon to reject a coerced confession and expose the plotters’ attempt to control the crown.

Arrests and the refuge at Maegor’s Holdfast

The crisis unfolded amid the collapse of House Rogare. In King’s Landing, Lotho Rogare had been arrested and the remaining valuables in his vault seized; Lord Roggerio was also taken into custody. At first, observers assumed Thaddeus Rowan, former Hand, had ordered the arrests. That explanation quickly failed: Rowan himself was arrested that evening, while Tessario the Tiger and the men under his command did nothing to protect him. Ser Mervyn Flowers took Rowan into custody, and the only resistance came from Rowan’s squire, who was quickly overcome. Rowan pleaded for the boy to be spared, but Flowers had already injured him before allowing him to live.

The arrests extended to Rowan’s relatives and household. Three cousins and a nephew, along with many servants, grooms, and retainers, were seized. When Ser Amaury Peake arrived at Maegor’s Holdfast with armed men to take Lady Larra Rogare for questioning, Viserys stood on the drawbridge with a battleaxe and refused to let them pass. Aegon III was also inside. Amaury treated the resistance as a challenge he could readily overcome and ordered his men to move the two boys aside, while directing them not to harm them.

Viserys warned Amaury again and drove the axe into the drawbridge as a boundary. Aegon drew his brother back into the holdfast, and Sandoq stepped forward. Sandoq had come from Lys with Lady Larra, a gift from her father, Lysandro Rogare. In the ensuing fight, he used a large shield and a curved sword with a dragonbone hilt. He stopped the attackers from crossing the bridge; when an opposing guard disarmed him, Sandoq pulled Viserys’s axe from the wood and used it to defeat Amaury. The king then ordered the drawbridge raised, the portcullis lowered, and the gates barred. Maegor’s Holdfast became a defensible refuge within the Red Keep.

The eighteen-day standoff

The holdfast remained shut for eighteen days. Outside it, Ser Marston Waters and his Kingsguard controlled the rest of the Red Keep, while Ser Lucas Leygood and the gold cloaks held King’s Landing. Their forces greatly outnumbered the people inside the holdfast. Its defenders included Sandoq and only six other Lyseni, a few men loyal to Rowan, and the royal household. The disparity made an assault appear possible, but Waters continued trying to end the confrontation through negotiation rather than storming the stronghold.

The account presents his restraint as a conflict between power and obligation. Waters had risen from a modest position to become Lord Commander of the Kingsguard and Hand of the King. One explanation for his hesitation is that he would not order an attack on the king he had sworn to protect, even while claiming to act in the king’s interest. The possibility that the holdfast’s supplies would run low offered another reason to wait. The siege thus turned not only on the strength of its walls but on competing interpretations of loyalty: Waters claimed to defend Aegon, while Aegon remained inside with the people Waters’s side was trying to arrest.

On the twelfth day, Rowan was brought out in chains to confess. Septon Bernard recited a long list of accusations: bribery, interference in the Vale succession, a conspiracy to remove Unwin Peake as Hand, theft connected with the Rogare Bank, and the appointment of Rowan’s son to a command blamed for heavy losses. The gravest charge was that Rowan and the Rogares had plotted to poison Aegon and the queen, place Viserys on the Iron Throne, and make Lady Larra queen. Bernard identified the poison as Tears of Lys and connected the alleged plot to the death of Gaemon Palehair.

Rowan then appeared to confirm the accusations, including that Lotho had promised him money and that Roggerio had supplied the poison. But his condition and manner raised doubts: he spoke haltingly, and his face was too swollen to recognize. Viserys asked whether Lady Larra and he himself had been part of the plot. Rowan said they had. Viserys then pointed out the absurdity of implicating Gaemon, and Rowan also admitted to poisoning King Viserys. The accumulating confession did not persuade Aegon. Instead, the king declared Rowan innocent of treason and identified the men who had tortured him as the traitors. He ordered Waters to seize the Lord Confessor, George Graceford, or prove himself false to the king. At that moment, Aegon’s response changed the meaning of the standoff: the boy who had been kept behind the gates spoke with the authority to direct events outside them.

The conspiracy unravels

Waters followed the king’s order. Graceford was taken into custody, Rowan’s chains were removed, and Rowan’s men were released from the dungeons. The sight of the instruments of torture was enough to make Graceford name others whom he said were involved. The list included the late Amaury Peake, Mervyn Flowers, Tessario the Tiger, Septon Bernard, Gareth Long, Victor Risley, Lucas Leygood and several city-gate captains, as well as three of the queen’s ladies.

The arrests did not proceed without further resistance. Men sent for Leygood met a brief fight at the Gate of the Gods in which he was killed. Some accused captains escaped with their men. Tessario tried to flee by arranging passage aboard an Ibbenese ship near the River Gate, but was caught. Waters confronted Flowers himself. Flowers attacked him during their encounter, then fled toward the stables; he was killed after killing a man-at-arms and two stableboys. These reversals further weakened the men who had controlled the castle during the siege.

Suspicion also fell on Unwin Peake as a possible organizer operating behind the accused. Several alleged conspirators had family ties to him or owed their positions to him, and Peake had previously been associated with a conspiracy against dragonriders. Yet he was at Starpike during the siege, and none of the named suspects implicated him. His involvement therefore remained a suspicion, not an established fact.

Aftermath and significance

Aegon did not leave Maegor’s Holdfast immediately after Rowan’s confession was overturned. The mistrust inside the Red Keep persisted for six more days, and food had grown so scarce that Queen Daenaera and two of her ladies were suffering from hunger. Aegon agreed to lower the bridge only after Grand Maester Munkun sent out ravens summoning forty loyal lords to King’s Landing. By then, Graceford had named alleged accomplices, several suspects had been captured, and Waters, Flowers, and Leygood were dead.

Rowan returned to the Tower of the Hand but was too damaged by his imprisonment to resume his duties. A month later, Munkun persuaded Aegon to relieve him of office. Rowan set out for Goldengrove, intending to return after recovering, but died on the journey with two of his sons. Munkun served as both regent and Hand for the rest of the year. The accused conspirators remained imprisoned while the realm awaited a new Hand willing to judge the cases of powerful lords and knights.

The siege’s decisive reversal came not from an outside army but from the king’s refusal to accept a confession extracted from his own Hand. Its course exposes how an apparently orderly list of charges could serve as a weapon in a struggle over access to the king and control of the regency. Yet the account does not settle every question: the suspected role of Peake remains unproven, and the responsibilities of some of the named conspirators are presented through contested testimony. The holdfast’s confinement preserved Aegon’s ability to speak for himself; his judgment, in turn, broke the immediate attempt to make a coerced confession the basis of royal authority.
