Saving the Baghdad Zoo: A True Story of Hope and Heroes by Kelly Milner Halls and Major William Sumner

From chapters.ca:
The baghdad zoo was once home to more than six hundred magnificent animals. But after the war in Iraq began in 2003, the city faced widespread destruction. When U. S. Army Captain William Sumner was asked to check out the state of the zoo, he found that it, too, was devastated. Hundreds of animals were missing, and the few remaining were in desperate need of care. And so Captain Sumner accepted a new mission. Together with an international team of zoologists, veterinarians, conservationists, and dedicated animal lovers, Captain Sumner worked tirelessly to save the neglected - but tenacious - animals of Baghdad.
