The narrative begins with Sophie providing a detailed account of her visit to the "giant country" to the Queen. The Queen, initially "appalled" by the news, treats the information with the gravity it deserves. To verify the BFG’s claims, the Queen orchestrates a diplomatic call to the King of Sweden. The revelation that twenty-six of his "loyal subjects" have vanished confirms the BFG’s report that the "man-eating brutes" have indeed been hunting humans for their taste, which the King describes as preferring the flavor of "Swedes." This interaction serves as the turning point where the BFG’s testimony shifts from a bizarre fantasy to a verified existential threat to humanity.
Once the threat is confirmed, the Queen summons the heads of the army and air force. A conflict in philosophy immediately arises: the military leaders advocate for lethal force, suggesting they "mow them down with machine guns" or "bomb them." However, the Queen displays moral leadership, stating firmly, "I do not approve of murder." She insists that the giants must be brought back "alive," rejecting the idea of following the "murderers" into moral depravity.
The BFG provides the tactical ingenuity required to capture the fifty-foot-tall entities. Using his unique vernacular, he explains that the giants spend their afternoons in the "land of Nod" (the land of sleep), providing a window of opportunity to "creep up" and bind them. He proposes using "belly poppers"—his term for helicopters—to transport the giants. His plan is both simple and brilliant: rather than trying to fit the giants inside the aircraft, the military should "sling" them "underneath the belly" of the helicopters. This logistical masterstroke allows the air force to mobilize nine helicopters, one for each giant, following the BFG as he "gallops" toward their territory.
The final phase of the operation involves a journey beyond the known world. As the helicopters follow the BFG, the military leaders realize they have "flown clean off the last page" of their maps, entering a desolate landscape where the "trees are dead" and the "rocks are blue." This transition into the "Great Yellow Wasteland" underscores the otherworldly nature of the giant country.
Before departing, Sophie requests to ride in the BFG’s ear, cementing their bond. Furthermore, the BFG makes a touching request to save his "collection of dreams," which he has spent "years and years to collect." The Queen’s gracious consent to this request highlights the humanity of the BFG, who, despite his size and the monstrous nature of his kin, values the ethereal beauty of dreams. The story concludes with the landing of the helicopters and the deployment of jeeps armed with "thick rope and heavy chains," setting the stage for the final confrontation between the organized forces of the Queen and the chaotic, man-eating giants.
