We couldn't, thinks ex-Marine Sergeant Manchester, take Tarawa again (or Guadalcanal or Iwo Jima or Okinawa): today's young wouldn't plod "patiently on and on"--chest-deep in water, weapons over their heads, keeping formation"--while their comrades were keeling over on all sides." That isn't the only message of Manchester's return, in memory and in person, to Pacific battlegrounds, but it's the one that forces a yea or nay from the reader--while one can easily remain indifferent to (even skeptical of) Manchester's personal quest for the reason he left a hospital bed, before Okinawa, to rejoin his men: it was--climax-of-book--"an act of love." The entire reconnaissance, he says, was touched off by the appearance in his dreams of his young, tough, uncompromising self reproaching his present "portly, Brooks-Brothered" mid-fifties self: "what had happened in the third of a century since he had laid down his arms?" We then back up to the distinguished Manchester lineage; his (wounded) Marine veteran father and Old-Southern mother; his timid, picked-on childhood; his auspicious start at Amherst; his early enlistment in the Marines, love of rugged Parris Island, hatred of competitive Quantico OCS (he wittingly washed out); his hookup with the "military misfits"--most of them "liberal arts majors from old eastern colleges"--whose sergeant he was slated to be; and his two pre-embarkation attempts to lose his virginity (both aborted--one in party by "my outsize genitalia"--and neither quite credible). Also worked into the foregoing are the attack on Pearl Harbor, the loss of the Philippines, and the Herculean securing of New Guinea--which brings the Pacific War, and Manchester's unit, to Guadalcanal. And whatever one thinks of both stories-so-far (or of the coupling--a kind of personalized pop history), the subsequent chronicle of debilitating jungle warfare on one after another "dumb island" (as a fed-up Marine put it) has an undeniable impact--not because the botched landing at Tarawa, for instance, is news, but because time has diminished neither the horror nor Manchester's outrage. At first, too, his reference to the Japanese as "Japs" or "Nips" rankles; and one recoils when he writes, early on, "thank God for the atomic bomb." But his description of Japanese tactics--first the suicide attacks, then the suicidal last stands--demonstrates why he's still appalled at the prospect of storming mainland Japan. Similarly, what he finds on these islands now is of varying interest or noteworthiness (the native culture corrupted; Japanese tourists and/or businessmen) until he reaches Saipan, where Allied forces first encountered Japanese civilians; at the island's fall, all 18,000 hurled themselves off two cliffs . . . and their bodies are still being recovered and cremated, so the ashes can be returned to Japan. The eventual death of most of Manchester's men on Okinawa's Sugar Loaf is more immediate but not more unnerving. And his farewell to his Sergeant-self--atop today's built-over Sugar-Loaf--seems if anything a cheapening artifice. As for the upright, moral, industrious pre-WW II America that he deems responsible for his generation's sacrifice, it will not be recognized by many of his contemporaries ("Mothers were beloved, fathers obeyed"; "To accept unemployment compensation, had it existed, would have been considered humiliating"); and to Americans of any age, it might appear a misguided ideal. But one can dissent from much of this and still be shaken.
