Yeah, but that was walls of dead
zombies that the walkers had to climb over. They weren't climbing over still-moving zeds in a reanimated tsunami of flesh and bone or forming towers to reach survivors.
And there were outposts in the book that lasted through the conflict by simply barricading themselves in. I'd cite specific examples but I don't have my copy of the book here, I loaned it out to a friend to read. But off the top of my head I remember the Brits and Russians had at least one fortress apiece that held against the zombies until the main forces were able to recover and return.
