The Battle of Anzio left the marsh in state of devastation; nearly everything Mussolini had accomplished was reversed. The cities were in ruins, the houses blown up, the marshes full of brackish water, the channels filled in, the plain depopulated, the mosquitos flourishing, and malaria on the rise. The major structures for water control survived, and in a few years, the Agro Pontino was restored. In 1947, the province of Littoria, created by Mussolini, was renamed to Latina. The last of the malaria was conquered in the 1950s, with the aid of DDT.
