Zouga lifted his right hand to salute her achievement.
it had been a tremendous run, to make up so much ground. He was turned slightly towards her, and her expression of cold disinterest lulled him for the vital instant that it took her to bring Shooting Star level with Tom's shoulder.
Zouga never saw the command, probably the toe of her boot on the far side of Shooting Star's heaving chest; he had certainly not expected a show horse to have learned the low tricks of a polo pony. Shooting Star's huge sweat-streaked shoulder crashed into Tom, taking him in the short ribs with a force that drove the air out of him in a belching grunt, and as he was spun aside Tom chopped desperately to keep from falling, twisting and dropping to his knees, his nose on the ground, too tired and taken too unawares to meet the power of that ferocious barge.
Zouga lost a stirrup and was thrown onto Tom's neck.
He clung desperately, feeling the saddle shift under the unequal transfer of weight; then Tom heaved again and Zouga went over, landing on his shoulders and the back of his neck.
He seemed to strike solid rock and blackness crushed down from the dome of his skull. When it cleared, he was standing again, swaying like a drunk, blinking uncertainly after the pounding stallion as he pulled away towards the last flag.
Zouga pulled Tom to his feet, and checked swiftly for strained sinew or broken bone, then threw himself back into the saddle.
'We're not beat yet,' he told Tom 'There are still the thorns.'
Far ahead Shooting Star was making the turn around the last flag. From there Louise was free to make her way back to the finish line any way she wanted, but there were still the thorns.
Tom was winded, his chest shuddering with the effort of each laboured breath, and they reached the flag in an awkward jarring trot and made the turn. Ahead of them the thorns stretched in a solid green barrier. This was the last obstacle, and beyond it was a clear run to the finish.
A rider had a choice: go through the thorn, or ride wide.
'Which way did she go?' Zouga shouted at the stewards below the flag as he went past.
'She's gone for the gap,' one of them yelled back, and then Zouga saw the little feather of dust a mile or more out on the right subsiding only slowly as the stallion sped away.
The thorn barrier petered out on the rocky slopes of the Magersfontein hills, and there was an open gap below the steep ironstone cliffs, that was where the stallion was aimed.
Grimly Zouga swung Tom around the flag and pointed him directly at the thorns. This route was almost two miles shorter, but he would need every inch of it. Yet he stopped Tom when they reached the edge of the thorns and let him breathe as he untied the heavy greatcoat from the pommel of his saddle and shrugged into it. He buttoned it high at the throat and felt the sweat burst out on his forehead as he pulled on the leather gauntlets to protect his hands.
'Let's go,' he whispered, and lay flat on Tom's neck, as they crashed into the thorn.
The red-tipped hooked points of the thorns skidded over Zouga's thick felt hat with a rasping tearing sound, and tugged at the shoulders and skirts of the greatcoat.
The brush grew as high as a mounted man's head, the sturdy trunks just far enough apart to let a horse pass, but the barbed branches intertwined and exacted a cruel toll. However, Tom kept going, swinging and chopping from side to side; he dodged between the white barked trunks, ducking his head under the branches, his ears flat against his skull and his eyes closed to slits, maintaining just the right amount of momentum to snap the thorns off their triangular bases and showering both himself and Zouga with a confetti of feathery green leaves.
Every few seconds he snorted at the sting of thorn that had penetrated his tough shaggy hide.
Shooting Star's burnished skin was so thin and finely bred that the network of veins and arteries showed through it. The thorns would have ripped it to bloody tatters.
Zouga felt blood trickling down his own neck from where a thorn had nicked his ear, but he crouched lower and let Tom pick his own way through. 'Poor Tom,' he encouraged him. 'Poor brave Tom.' The horse whickered with the pain of the stinging red needles, but did not check his stride. Yet his breathing was easier now, the slower gait had helped him; and the sweat was drying in salty white crystals on his shoulders.
Then abruptly they burst out of the thorn onto the open plain. Zouga tore off the leather gauntlets and threw them away. He ripped at the buttons of the greatcoat and let it fly away, flapping like a great black crow in the wind of Tom's gallop, and then he stood high in the stirrups and shaded his eyes with the brim of his hat.
Swiftly he searched the open ground, but it was empty as far as he could see. the tiny specks of colour in the distance: women's dresses and the gay bunting that marked the finish. His heart bounded with relief, and under him Tom lunged into a clumsy gallop.
Still standing in the stirrups, Zouga looked towards the line of hills out on his right hand, and he saw them.
The stallion had turned the far end of the thorn barrier where it ran into the hills and was coming down the rocky slope towards the level ground in a dangerous scramble.
The tiny figure on his back was being thrown about brutally. One instant she seemed to be on his neck, the next she was flung back onto his haunches, as Shooting Star plunged and heaved to keep his balance.
'We have them now, Tom. There it is. There is the line, right under your nose.' Zouga pointed his head.
'They cannot catch us now. Go, old man, go!' Tom's hooves cracked on the hard earth like the beat of a joyous drummer. The crossing of the thorns had been cruel work, but it had rested him and he was pushing hard now.
'Waie hole!' Zouga called to him, and Tom flicked his ears reproachfully. He had seen it before Zouga had, and he jinked around the burrow neatly, while the heads of the curious little ground squirrels bobbed out of the earth as they passed.
The ground was rotten with their warrens, but Tom barely checked his gallop, swinging to avoid the mounds of
