The second volume of Thomas Whigham's history of the Paraguayan War picks up where his previous volume, Causes and Early Conduct, left off, with the forces of the Triple Alliance — Brazil, Argentina, and Uruguay — preparing to invade Paraguay after having driven Paraguayan troops out of Argentina. Though the Paraguayans initially checked the Alliance's advance, their defeat at the battle of Tuyuti devastated their army. Yet while the leaders of the Alliance expected such a loss to result in Paraguay's surrender, the Paraguayan dictator Francisco Solano López refused to accept terms which required him to give up his position, thus dooming Paraguay to a drawn-out and destructive defeat.
As Whigham explains, a key factor behind Paraguay's ability to endure for so long was its cohesion as a population. With their nation under attack, López was able to mobilize the population to sustain a seemingly unimaginable war effort. With Paraguay's access to the outside world cut off by an Alliance blockade, the Paraguayans were forced to undertake extraordinary expedients in order to sustain their war effort. Yet not even the total mobilization of their population could overcome the increasingly capable Alliance forces from taking the fortress of Humaitá in 1868 and capturing the Paraguayan capital in the new year. Only with López's death in March 1870, though, did the war finally come to an end, with ramifications to be felt for decades to come.
The product of years of archival labors and writing, Whigham's book is a superb account of a war too often underappreciated in the north. With a narrative that reflects the tragedy (and even absurdity) of the conflict, he captures well its epic nature while analyzing the various factors at work in the conflict, from the command structures to logistics and medical care. Together the two volumes combine to provide readers with the definitive study of the Paraguayan War we have long needed, one that nobody interested in the subject can afford to neglect.
