The narrative begins with Black Beauty’s transition into his new role as a cab horse under the ownership of Jerry, a kind and diligent master. Life in the city is initially overwhelming for Beauty; he describes the experience as "difficult" due to the constant "noise, the hurrying, and the crowds of horses, carts, and carriages" that made him "very nervous." However, the bond between horse and driver quickly matures. Beauty learns that he can "trust" Jerry, who ensures the harness fits perfectly so that it is a "relief" to be comfortable while working. Jerry’s gentle approach, marked by the absence of the whip, allows them to develop a mutual understanding, supported by Jerry’s commitment to providing "clean" stables and "plenty" of fresh food and water.
Central to Beauty’s new environment is his companionship with Captain, an "old war horse" who possesses a "proud way of holding his head." Their friendship deepens during their "Sundays for rest." Captain serves as a mentor figure, sharing harrowing tales from his past service as a cavalry horse during the Crimean War. Through Captain’s recollections, the reader gains insight into the stark contrast between the perceived nobility of war and its brutal reality. Captain describes the physical toll of military service, including the traumatic transport across the ocean where horses were "strapped" and confined in "small stalls" without access to the "sun or sky."
Captain’s most poignant testimony concerns the nature of combat. He explains that as long as the riders held the "reins" with "steady" hands, the horses could suppress their fear. However, the "autumn morning" of the final battle remains etched in his memory as a moment of absolute "terror." He recounts the deafening sounds of "cannons, muskets and heavy guns" that filled the air. The climax of his trauma occurs when his master, who had been "cheering on his soldiers," is struck by a "cannonball." Captain describes the visceral heartbreak of feeling his master’s sword fall and being forced to move on with the retreating line, unable to protect the man he loved.
Following Captain’s story, the dialogue shifts to a philosophical reflection on the nature of human conflict. Beauty observes that while society often speaks of war as a "noble thing," those who hold such views "have never really seen war." Captain’s firsthand account of "brave men and horses" being "killed or hurt for life" serves as a somber rebuttal to the romanticization of battle. The conversation concludes with a profound observation on the limited perspective of animals; Beauty notes that a horse cannot understand the complex geopolitical reasons for war. Captain reflects that the enemy must have been "very wicked" to justify such extreme measures, yet the suffering endured by both man and beast remains the only truth he truly understands. This chapter serves as a powerful meditation on trust, the trauma of history, and the quiet dignity of those who endure the burdens placed upon them by human ambition.
