‘Can’t you go ashore somewhere else, not at the Residence?’
Again Benjamin shook his head. ‘We are Laptots. We were brought to St Louis as slaves, and our own homelands are far away. The local people would not accept us. Besides, without us you will never cross the bar.’
‘What do you mean?’
‘There are many sandbanks and mud shoals where the river runs into the sea. Ships can come in and out when the river is in flood, but now it is almost too late. This is the season when the sea breaks heavily on the bar, and it is very dangerous. It needs local knowledge to find a way through the obstacles and a travado to help us.’
‘A travado?’
‘A great gale of wind from the north-east, from the desert. The wind blows opposite to the sea, and drives back the waves. Also the ship is pressed forward and crosses the bar quickly.’
‘Then we must all hope for a travado.’
Benjamin appeared to hesitate, then asked, ‘Once we are out to sea, who will show us the way, who will navigate the ship? You said you were not a ship’s captain, but now you are sounding like one.’
Hector found himself saying nervously, ‘I’ve never navigated a ship before. But I think I can learn.’
WITH THE RIVER CURRENT sweeping her along, L’Arc-de-Ciel took less than a week to reach the bar at St Louis. Hector spent much of the time studying the dead captain’s sea charts and trying to understand his navigation instruments. The main item was a mystifying device as long as his arm and carefully stored in a cherrywood box. Its open frame supported two wooden arcs engraved with degrees of angle. Three small vanes were attached to each of the arcs, and he found he could slide the vanes back and forth. One of them was fitted with a lens. Puzzled, he took the instrument on deck and tried to use it. But it defied logic. He held the instrument up to his eye and tried looking through the lens. Then he slid the vanes to different positions. The angles they recorded made no sense. He turned the device around, and tried looking through it the other way. Still nothing worked. Bourdon strolled over to see what he was doing, and commented that he had seen an architect using something similar when he had visited the building work at Versailles. ‘It’s for measuring angles,’ he commented. ‘I know that already,’ snapped Hector, increasingly frustrated. ‘If I could use it to find the angle of the sun or of the north star, then it would be better than the astrolabe I learned to use among the Turks. There’s a book of tables among the captain’s possessions which gives the height of the sun or the star at different locations at different times of the year. With that knowledge I might even be able to take us to the Caribees.’
The Frenchman tactfully withdrew, leaving Hector to wrestle with his problem. Unexpectedly Benjamin provided the solution. He had seen the captain of a visiting ship use a similar gadget. Benjamin had thought the captain was touched in the head, for he had held the instrument to his eye in broad daylight and when facing out to the open sea. There was nothing on the horizon to look at. ‘You must be wrong, I’m sure he was measuring the angle of the sun,’ Hector growled. He was really irritated now.
‘No,’ the Laptot insisted. ‘He was looking out to sea. The sun was behind him.’
To save his dignity, Hector waited until Benjamin had walked away before, still doubtful, he turned his back to the sun, peered through the lens, and fiddled with the vanes. By chance he saw the shadow of a vane pass into vision and across a graded arc. He lifted the instrument until it was level with the horizon and adjusted the vanes again. He placed the vane’s shadow steadily on the arc, then brought the instrument down and took the reading. It was in the range of numbers in the captain’s book of tables. He had discovered how to bring the ship to her destination.
They stopped only once on the river voyage, a brief halt at a friendly village to take fresh supplies and top up their water barrels. Then they dropped downriver until they began to feel the rise and fall of the tide, and Benjamin warned that the Residence of St Louis lay just ahead. ‘We must stay close to the left-hand shore. The guns of the Residence do not reach that far. A few ships will be anchored in the roadstead, maybe a man of war also, but we can slip past them if the wind favours us.’ He pointed to the north. A small dark cloud could be seen, far in the distance. ‘I think we are lucky with the weather.’
As the day wore on, banks of thick, dark cloud formed on the horizon and began to coalesce into a solid black mass. From the underbelly of the clouds flickered distant flashes of lightning. Along the river there was an atmosphere of foreboding. The breeze dropped away and was replaced by an oppressive calm. The air seemed to thicken and become slightly opaque. It was difficult to breathe. The sloop glided on, her sails slack, carried only by the current. Hector listened carefully. There was a faint roaring sound far away. ‘What’s that noise?’ he asked Benjamin. ‘That’s the sound of the waves breaking on the bar. Let us hope that the travado reaches us before we are in the overfalls, and that the ship survives the wind.’
Half an hour later the storm broke. There was a tremendous thunderclap and a great gust of wind swept across the river, driving spray from the surface. The squall struck the sloop like a fist. With a loud clap of canvas, the mainsail bellied out, and the sloop heeled over. Hector heard the groan of the stays under the sudden strain. L’Arc-de-Ciel surged forward as Dan and Benjamin struggled to control her helm.
A peal of thunder close at hand, and suddenly the horizon was blotted out by torrential rain which reduced visibility to a few paces. Hector’s clothes were saturated in an instant. He remembered the long parched days in the desert and tilted back his head in sheer delight. He opened his mouth and let the rain pour in. When he swallowed, he could taste the faint grains of dust which the travado had brought from the interior. Benjamin appeared at his side, gripping him by the elbow. ‘Go help Dan at the helm,’ he shouted. ‘I will show which way to steer.’
When Hector reached the wheel, Benjamin was already standing in the bow, peering into the murk. He raised his arm and pointed away to starboard. Obediently they steered to his instructions. Now the rain was hissing down, ochre rain on a brown river, and it was impossible to tell where the air and water met. More thunder, a massive growl which seemed to shake the sloop. A tremendous crack of lightning split the gloom.
Moments later the sloop was bucking and lurching as she was caught in the overfalls. Out of the murk raced a continuous onslaught of breaking waves. A lightning flash close at hand lit their foaming crests and turned them blinding white. L’Arc-de-Ciel surged on, the wind driving her forward. Benjamin gestured again, urgently this time, and Dan and Hector spun the wheel to bring the ship on her new course. There was no pattern to the waves breaking on the bar. They came from different directions, now smashing into her bow so she was tossed backwards, now heaving up along her sides so that she slewed sideways.
They never glimpsed St Louis. For two hours they battled with the overfalls, trusting to Benjamin’s directions, ploughing onward until they were sure that the turbulence was easing. Then the little ship ceased her wild gyrations and, though she still pitched and rolled uncomfortably, there was no mistaking that she was sailing on smoother water.
By nightfall the rain had ceased. The sky was still overcast so it was impossible to tell when the sun set, but the wind had eased to a moderate breeze and the air felt washed and clean. Benjamin came back from his lookout in the bow, and announced that they had cleared the bar and passed through the anchorage as well. They were in open water. Hector went down to the cabin and brought up the ship’s compass and set it down beside the helm. ‘Steer west,’ he said to Dan. ‘Tomorrow I will check the charts and set course for the Americas.’ He looked up at the sky. As swiftly as it had arrived, the travado had swept onward and out to sea. The first stars were showing through rents in the clouds. He thought he recognised the constellation of Orion. Now he would use its stars to find his way across the ocean. He gave a slight shiver of apprehension. There was so much to learn, and it was so easy to make mistakes. He thought back to Ibrahim, his corpse lying on the sand and the crusted blood of the wounds where the Labdessah had speared him to death, because he had followed Hector’s plan to ambush the Tooarick. And he recalled his last glimpse of Karp, the glint of the scimitar as it descended in a killing stroke. Poor mutilated Karp had believed in peace and forgiveness to the end, refusing to resort to violence even as he found a way to save his friends. Despondently Hector wondered if Dan and Jacques had been wise to place their trust in him. Too often he seemed to bring death and suffering upon his comrades.
