Chart of the Track of the Alexander
16 July 1788
At eight, A. M. on the 16th of July, the rocks off the entrance of Port Stephens bore north-west by west distant three leagues. Lieutenant Shortland very much regretted that this place had not been surveyed; had it been known to afford safe anchorage, it would have been much more prudent to put in there and wait for a change of wind, than to attempt keeping the sea in circumstances so very unfavourable, with ships so little calculated to run along a great extent of lee shore. This day the Prince of Wales being two or three miles to the leeward, the signal was made for her to tack into the fleet. At nine in the evening the wind coming to the east-south-east, Lieutenant Shortland fired a gun, and made the signal to veer ship and sail on the other tack. At this time the Prince of Wales was about five miles on the lee bow of the Alexander, and the Borrowdale and Friendship close in company; but by twelve at midnight the Friendship only was in sight. At two, the wind shifting again to the south-south-east, the signal was once more made to veer ship, and change the tack, as lying off east would clear the coast; a strong current setting to the southward.
19 July 1788
Lieutenant Shortland, having now lost sight of the Prince of Wales and Borrowdale, was fully determined to go to Lord Howe Island to wait a day or two for them, expecting that they might probably touch there with similar intentions. On the 19th, therefore, he steered a direct course for that island, with a strong gale at south-west, but as this wind, which was exactly favourable to the intended course of the voyage, and made the anchoring place off Lord Howe Island a lee shore, continued unvaried, and blew very hard on the 20th, it appeared best to relinquish the design of calling there. At two in the afternoon, therefore, Lieutenant Shortland again altered his course and sailed north-east by north. The Prince of Wales and Borrowdale transports, were seen no more throughout the voyage, and it has since been known that they took another course; but the Friendship continued close in company with the Alexander. About noon this day, the men at the mast head discovered a very extensive shoal on the larboard beam, bearing from north by west to north by south, distant between two and three leagues. It trended north by east and south by west, and was judged to be in length about three leagues and a half. The breadth could not be ascertained, for, while the ship ran along it, the sand bank was seen to extend as far as the eye could discern. It lies in latitude 29°. 20'. south, and in longitude 158°. 48'. east, and was named by Lieutenant Shortland, Middleton Shoals.
21 July 1788
At ten in the morning, on Monday July 21, the master of the Friendship went on board the Alexander, and Carteret's harbour in New Ireland, was appointed by Lieutenant Shortland as the place of rendezvous. The same day, at half past five in the afternoon, land was discovered, bearing from south-west by west, to west half south, at the distance of about eight leagues. It trended to the north-north-west, and was about six or seven leagues in length, the land very high, with a remarkable peak, which bore south-south-west. This island was now named Sir Charles Middleton's Island: It lies in latitude 28°. 10. south, and in longitude 159°. 50. east. Lieutenant Shortland thinks it probable that the reef seen on the preceding day may be connected with this island, as it trended in a right direction for it; but it must, in that case, be of very great extent. The island was still in sight on the morning of the 22d.
24 July 1788
On Thursday July 24th, they had an accurate observation of the sun and moon to determine the longitude, and found the effect of a current to have been so great as to set the ship two degrees of longitude to the eastward of the dead reckoning. The longitude of Sir Charles Middleton's Island must therefore be corrected by that observation, and placed considerably further to the east. The latitude may be depended upon, as the bearing was observed when the sun was on the meridian.
