Alas, Babylon is a 1959 novel by American writer Pat Frank (the pen name of Harry Hart Frank). It was one of the first apocalyptic novels of the nuclear age and has remained popular more than half a century after it was first published, consistently ranking in Amazon.com's Top 20 Science Fiction Short Stories list (which groups together short story collections and novels) and has an entry in David Pringle's book Science Fiction: The 100 Best Novels.

The novel deals with the effects of a nuclear war on the fictional small town of Fort Repose, Florida, which is based upon the actual city of Mount Dora, Florida, approximately 35 miles northwest of Orlando, Florida. The novel's title is derived from the Book of Revelation: "Alas, alas, that great city Babylon, that mighty city! for in one hour is thy judgment come." The cover art for the Bantam paperback edition was made by Robert Hunt.

Alas, Babylon

Plot

The story is set in a fictional 1959, following two years of escalating tensions between the United States and the Soviet Union for dominance in the Middle East and in the Mediterranean Sea. The Soviets are menacing Turkey from three sides through their proxies in Egypt, Syria and Iraq in order to gain control of the Bosporus and give free passage between the Black Sea and the Mediterranean to their large Mediterranean naval fleet.

Alas, Babylon

To counteract the Soviet menace the United States established a military presence in Lebanon and is providing aid to their Turkish and Israeli allies.

Alas, Babylon

As detailed in the book, the Soviets gained a temporary space supremacy through the launch of a massive fleet of militarized Sputniks; moreover, they are aware that, within three or four years, the United States will cover the gap. Intelligence from a Soviet officer who defected in Berlin provided information about a Soviet war plan involving a sudden, overwhelming nuclear first strike on U.S. and NATO military and civilian targets, in order to minimize retaliation and so that the Soviet Union can become the leading world power. According to the leaked war plan, the Soviet leadership considers acceptable the loss of 20 to 30 million of their own civilian population due to the retaliatory strike by NATO.

Narration follows the point of view of Randy Bragg, a failed political candidate and an attorney who occasionally practices law who otherwise lives an aimless life in the small Central Florida town of Fort Repose. The younger bachelor son of a prominent local family, his ancestors founded Fort Repose in the 1800s. His love interest is Elizabeth "Lib" McGovern, a single socialite who has recently moved to Florida from Cleveland, Ohio following her parents' retirement and relocation from Cleveland to Fort Repose.

Randy's older brother, Colonel Mark Bragg, a U.S. Air Force intelligence officer at Strategic Air Command (SAC) headquarters at Offutt Air Force Base in Omaha, Nebraska, sends a telegram to Randy ending in the words, "Alas, Babylon", a pre-established code between the brothers to warn of imminent disaster. Shortly thereafter, Mark flies his family down to Orlando in order to stay with Randy at Fort Repose for their protection while Mark remains at SAC headquarters at Offutt.

Soon afterwards, a carrier-based U.S. Navy fighter pilot, attempting to intercept a Soviet plane over the Mediterranean, inadvertently destroys an ammunition depot at a large Soviet submarine base in Latakia, Syria. The explosion is mistaken for a large-scale U.S. air assault on the military facility and, by the following day, the Soviet Union retaliates with its planned full-scale nuclear strike against the United States and its allies. With Mark as a witness, U.S. intercontinental ballistic missiles are launched at the Soviet Union in retaliation. Randy and his guests awake to the shaking from the nuclear missile attacks on nearby military bases such as McCoy Air Force Base in Orlando and Naval Air Station Sanford; one explosion temporarily blinds Peyton, Randy's niece. The residents of Fort Repose later observe other mushroom clouds to the southwest and northeast indicating that MacDill Air Force Base and the city of Tampa as well as the city of Jacksonville and its multiple U.S. naval installations have also been destroyed.

Following what is simply referred to as "The Day," Fort Repose descends into chaos: tourists are trapped in their hotels, communication lines fail, the CONELRAD radio system barely operates, convicts escape from prisons and a run on the banks makes currency worthless.
