Columbus Day recap

When the Ruhar attack Earth on Columbus Day, U.S. Army sergeant Joe Bishop survives the invasion and later joins a human expedition sent out with the Kristang, the aliens presented as Earth's rescuers. On Paradise, human troops discover that they are expendable auxiliaries in a much older war. Bishop's rise through the ranks ends in confinement, where he meets Skippy, an ancient and extraordinarily powerful artificial intelligence housed in a canister. Skippy reveals that humanity has misunderstood both the war and the danger surrounding Earth. He helps Bishop escape, gather a multinational team, and seize an alien starship that they rename the Flying Dutchman. The newly formed Merry Band of Pirates uses secrecy, raids, and Skippy's control of advanced systems to get the vessel home without exposing Earth. Their return brings warning and technology, but no lasting safety: discovery by the senior alien powers could doom humanity. Bishop and his crew consequently leave Earth again aboard the Dutchman to protect the secret and keep hostile attention away from their planet.

On Columbus Day, U.S. Army sergeant Joe Bishop is home in Maine when alien troops descend on Earth. The invaders are Ruhar, compact furred aliens whom the soldiers nickname hamsters. Bishop survives the sudden attack and helps resist with whatever weapons are available, but humanity has no effective answer to a force that arrived from space. A second alien species, the reptilian Kristang, then drives the Ruhar away and presents itself as Earth's rescuer. The apparent liberation comes with an invitation that is difficult to refuse: human troops can join the Kristang side of the interstellar war and help keep the enemy away from Earth. Bishop deploys with the resulting multinational force, leaving a damaged and bewildered planet for alien transport and training at Camp Alpha. The humans know almost nothing about the powers employing them, their technology, or the reasons Earth became a target, but most accept the Kristang account because it is the only explanation being offered.

Bishop and the expeditionary force travel to Paradise, a habitable world contested by the Kristang and Ruhar. The Kristang place the humans in ground positions and provide only limited information, treating their new allies as inexpensive infantry in a conflict fought with technology far beyond human experience. Combat on Paradise quickly exposes the gap between the public story of noble rescuers and the Kristang officers' indifference to human losses. Bishop's ability to improvise under pressure becomes increasingly important as isolated troops try to defend their positions with inadequate support. Human communications, transport, and intelligence all remain subject to alien priorities, leaving even senior officers with little independent knowledge. At Fort Arrow, Bishop helps keep a bad tactical situation from becoming a disaster. The experience convinces him that the expedition cannot assume its alien commanders value human lives or are telling the truth about the war, even though open resistance would leave the force stranded far from Earth.

Bishop's success at Fort Arrow brings an extraordinary promotion, placing a young soldier in a rank he never expected and under scrutiny from both human and Kristang commanders. Rank does not give him real control over the expedition's situation: the humans remain dependent on the Kristang for transport, supplies, and any route back to Earth. He continues using practical, unconventional solutions to keep troops fed and functioning while the campaign shifts around them, but initiative is unwelcome when it exposes failures in the official plan. His unwillingness to accept alien orders without question eventually puts him on the wrong side of the authorities. By the end of the ninth chapter he is confined, apparently cut off from any chance to help the force or learn why the war around Paradise does not match what humanity was told. The confinement instead places him near an object that the species fighting over the planet have failed to understand.

In confinement, Bishop hears a voice from a metallic canister and meets the artificial intelligence he names Skippy. The unassuming hardware contains an intelligence far older and more capable than the Kristang or Ruhar. Skippy is arrogant and evasive, but he can manipulate the advanced systems around them with ease. He explains that the local species are clients in a larger hierarchy and that humanity's supposed rescue does not make the Kristang trustworthy. Earth remains vulnerable, and revealing Skippy to the wrong power could make the danger much worse. Because his restrictions allow him to cooperate with a technologically primitive human in ways he cannot with the local spacefaring species, Bishop becomes the essential partner in an escape. With Skippy opening opportunities no human could create alone, Bishop gets free, recruits a compact multinational team, and begins the audacious task of taking an alien ship. The improvised unit becomes the Merry Band of Pirates, bound together by the need to act without alerting either side to Skippy or to their real objective.

Bishop's team seizes a starship and renames it the Flying Dutchman. Skippy can make its systems function and conceal much of what the humans are doing, but that does not turn the soldiers into an experienced space crew. They have to learn alien procedures while moving through hostile territory, and every use of the vessel risks leaving evidence that could be followed to Earth. Boarding actions, work outside the hull, and a carefully chosen raid give the Pirates equipment and information they need while helping to confuse the story of the ship's disappearance. Bishop's objective is no longer victory for either side on Paradise. It is to get the Dutchman and its human crew home, keep Skippy's existence secret, and prevent the alien powers from recognizing that humanity has gained access to technology it should not possess. By the end of the raid, the Pirates have a route toward Earth, but success depends on deception continuing to hold after they leave the immediate battlefield.

The Flying Dutchman reaches Earth with Bishop, Skippy, and the multinational crew. Their arrival confirms that the expeditionary force was used in a conflict humanity does not understand and gives Earth's governments knowledge they cannot safely acknowledge. Skippy warns that the Kristang and Ruhar are only lower levels in a hierarchy of far more capable species. If those powers learn that humans stole a ship, crossed interstellar space independently, or are sheltering an ancient artificial intelligence, Earth could be destroyed before it can defend itself. The Dutchman's return must therefore remain tightly concealed, and the ship cannot simply be displayed as the prize that brought the expedition home. After a brief period on Earth, Bishop accepts that protecting the planet requires the Pirates to operate beyond it. The crew prepares the captured vessel for another covert mission and departs again. The book closes with the Merry Band of Pirates outbound aboard the Dutchman, using Skippy's abilities and their own improvisation to preserve the secrecy that is now Earth's main defense.

Bishop, Skippy, and the human crew bring the captured Flying Dutchman to Earth, proving that the expeditionary force was drawn into an alien conflict under false assumptions. Skippy's existence and the theft of the ship must remain secret: humanity cannot yet survive the attention of the senior species whose clients are fighting the war. Returning home therefore does not end the mission. Earth gains access to alien technology and warning of the wider danger, but it cannot openly use either without revealing what happened on Paradise. With their families and governments informed only as far as security permits, Bishop and the multinational crew accept that they must go back into space. The Flying Dutchman departs Earth again with the newly named Merry Band of Pirates, relying on Skippy to conceal their movements while they work to prevent either side of the alien war from tracing the theft and the artificial intelligence back to humanity. Earth is temporarily safe, not secure, and Bishop's improvised force becomes its covert defense beyond the solar system.
