He came back to reality gradually, and he was aware that the sunlight had mellowed and the terrible heat had passed.

There was a tiny breeze fanning the hilltop and he panted for the cooler air, sucking it gratefully into his lungs. Then he became aware of his thirst and his hand shook as he reached for the water bottle; it required an enormous effort to remove the stopper and lift it to his lips. One gulp and the bottle slipped from his grip and precious water splashed the front of his shirt and glugged from the bottle, pooling on the rock, evaporating almost immediately. He had lost fully a pint before he could retrieve the bottle and the loss made him want to weep.

Carefully he screwed the stopper closed, then lifted his head and listened.

There were men on the hill. He heard the distinct crunch of a steel-shod boot biting into a granite foothold and he reached for one of the potato masher grenades. With the Mauser over his shoulder he crawled back from the edge and used the rock to pull himself to his feet. He could not stand unassisted, and he had to lean his way around the boulder.

He crept forward cautiously with the grenade ready.

The summit was clear; they must still be climbing the cliff. He held his breath and listened with all his being. He heard it again, close at hand, the scrape and slide of cloth against granite and a sharp involuntary inhalation of breath, a gasp of effort as somebody missed and then retrieved a foothold just below the summit.

They are coming up from behind, he told himself as though explaining to a backward child. Every thought required an effort. 'Seven-second delay on the fuse of the grenade. He stared down at the clumsy weapon that he held by its wooden handle. Too long. They are very close. He lifted the grenade and tried to pull the firing-pin. It had corroded and was firmly stuck. He grunted and heaved at it and the pin came away. He heard the primer click and he began to count.

A thousand and one, a thousand and two, And at the fifth second he stooped and rolled the grenade over the edge.

Out of sight, but close by, someone shouted an urgent warning.

Christ! It's a grenade! And Lothar laughed wildly.

Eat it, you jackals of the English! He heard them sliding and slipping as they tried to escape and he braced himself for the explosion, but instead he heard only the clatter and rattle of the grenade as it bounced and dropped down the slope.

Misfire! He stopped laughing. job damn it to hell. Then abruptly, but belatedly, the grenade exploded, far down the cliff. A crash of sound followed by the rattle and whine of shrapnel on the rock, and a man cried out.

Lothar fell to his knees and crawled to the edge. He looked over.

There were three khaki-uniformed men on the cliff, sliding and scrambling downwards. He propped the Mauser on the lip and fired rapidly. His bullets left lead smears on the rock close beside the terrified troopers. They dropped the last few feet and started back towards the trees. One of them was hurt, hit by shrapnel; his companions supported him on each side and dragged him away.

Lothar lay exhausted by the effort for almost an hour before he could drag himself back to the south side of the summit. He looked down at the dead horses lying in the sun.

Already their bellies were swelling, but the water bottles were still strapped to their saddles. The water is the magnet, he whispered. By now they will be really thirsty.

They will come for the water next. At first he thought the darkness was only in his mind again, but when he rolled his head and looked into the west he saw the last orange flash of the sunset in the sky. Before his eyes it faded and the sudden African night was upon them.

He lay and listened for them to try to reach the water, and he wondered as he had so often before at the mystic sounds of the African night, the gentle muted orchestra of insect and bird, the piping of the hunting bats flitting around the dome of rock and out on the plain the plaintive yip of jackal and the occasional outlandish grunting bark of the nocturnal honey badger. Lothar had to try to discount these distractions and listen for manmade sounds in the darkness directly below the cliff.

It was only the clink of a stirrup iron that alerted him, and he tossed the grenade with a full swing of his arm out over the abyss. The heavy crump of the explosion blew a puff of air into his face, and by the sudden flare of flame he saw far below the dark figures standing over the dead horse.

He made out two of them, though he could not be certain there were not others, and he tossed the second grenade.

In the brief burst of orange light he saw them racing back towards the trees; they ran so lightly that they could not have been burdened by water bottles.

Sweat it out, he taunted them, but he had only the one remaining grenade. He held it to his chest as though it were some rare treasure.

Must be ready when they come again.

Can't let them get the water. He was talking aloud, and he knew it was a sign of his delirium. Every time he felt the swimming dizziness he lifted his head and tried to focus on the stars.

Got to hold out, he told himself seriously. If I can only keep them here until noon tomorrow. He tried to make the calculations of time and distance but it was too much for him. Must be eight hours since Hendrick and Manie left.

They will keep going all night. They haven't got me to hold them back. They can make the river before dawn. If only I can hold them another eight hours they will get clear away But the weariness and the fever overwhelmed him and he cradled his forehead in the curve of his elbow.

Lothar! It was his imagination, he knew that, but then his name was called again. Lothar! And he lifted his head and shivered with the cold of the night and the memories that her voice summoned up.

He opened his mouth and then closed it. He would not reply, would give nothing away. But he listened avidly for Centaine Courtney to call again.

Lothar, we have a wounded man. He judged that she was at the edge of the forest. He could imagine her, determined and brave, that small firm chin lifted, those dark eyes.

Why do I still love you? he whispered.

We must have water for him. Strange how clearly her voice carried. He could pick out the inflection of her French accent and somehow he found that touching. It brought tears to his eyes.

Lothar! I am coming out to fetch the water., Her voice was closer, stronger, clearly she had left the shelter of the trees.

I'm alone, Lothar. She must be halfway across the open ground.

Go back! He tried to shout, but it was a mumble. I warned you.

I have to do it. He fumbled for the grenade.

Can't let you take the water, for Manie's sake. I have to do it. He hooked his finger through the firing ring of the grenade.

I have reached the first horse, she called. I am taking the bottle. just one bottle, Lothar., She was in his power. She was standing at the foot of the cliff. It wouldn't need a long throw. All he had to do was roll the grenade over the edge and it would fly out like a toboggan along the curve of the cliff and land at her feet.

He imagined the flash of the explosion, that sweet flesh that had cradled his, and harboured his son, torn and rent by razor-edged shrapnel. He thought how much he hated her, and realized that he loved her as much, and the tears in his eyes blinded him.

I'm going back now, Lothar. I have one bottle, she called, and he heard in her voice gratitude and an acknowledgement of the bond between them that no deed, no passage of time could sever. She spoke again, dropping her voice so it reached him as a faint whisper.

May God forgive you, Lothar De La Rey. And then no more.

Those gentle words wounded him as deeply as any he had ever heard from her. There was a finality to them that he found unbearable, and he dropped his head onto his arm to smother the cry of despair which rose in his throat, and the darkness rustled in his head like the wings of a black vulture as he felt himself falling, falling, falling.
