Joshua Hammer at the Wall Street Journal tells us about a guy in Timbuktu who did a lot to keep the city’s libraries, books and manuscripts out of the hands of al Qaeda in the Islamic Maghreb.

The story begins in April 2012, when [Abdel Kader] Haidara returned home from a business trip to learn that the weak Malian army had collapsed and that nearly 1,000 Islamist fighters from one of al Qaeda’s African affiliates, al Qaeda in the Islamic Maghreb, had occupied his city. He encountered looters, gunfire and black flags flying from government buildings, and he feared that the city’s dozens of libraries and repositories—home to hundreds of thousands of rare Arabic manuscripts—would be pillaged.

He has quite a book collection himself.

Mr. Haidara knew that many of the works in the city’s repositories were ancient examples of the reasoned discourse and intellectual inquiry that the jihadists, with their intolerance and rigid views of Islam, wanted to destroy. The manuscripts, he thought, would inevitably become a target.

They are people of One Book. People of One Book tend to be very dangerous.

He met with other librarians and archivists and suggested a plan to store books with individual families around the city, so that they wouldn’t be all together for ease of destruction.

And then he gave up his own interests for the sake of saving the archives.

Months earlier, the Ford Foundation office in Lagos, Nigeria, had given Mr. Haidara a $12,000 grant to study English at Oxford in the fall and winter of 2012. The money had been wired to a savings account. He emailed the foundation and asked for authorization to reallocate the funds to protect the manuscripts from the hands of Timbuktu’s occupiers. The money was released in three days. Mr. Haidara recruited his nephew, and they reached out to archivists, secretaries, Timbuktu tour guides and a half-dozen of Mr. Haidara’s relatives.

The result was a heist worthy of “Ocean’s Eleven.” They bought metal and wooden trunks at a rate of between 50 and 80 a day, made more containers out of oil barrels and located safe houses around the city and beyond. They organized a small army of packers who worked silently in the dark and arranged for the trunks to be carried by donkey to their hiding places.

Over the course of eight months, the operation came to involve hundreds of packers, drivers and couriers. They smuggled the manuscripts out of Timbuktu by road and by river, past jihadist checkpoints and, in government territory, suspicious Malian troops. By the time French troops invaded the north in January 2013, the radicals had managed to destroy only 4,000 of Timbuktu’s nearly 400,000 ancient manuscripts. “If we hadn’t acted,” Mr. Haidara told me later, “I’m almost 100% certain that many, many others would have been burned.”

Thank you, Mr Haidara and fellow rescuers. Thank you on behalf of humanity at large, and Mali and Malians. Well done.
