1798 The old chart of Dagelet

Although this is not directly related to Liancourt Rocks, I've obtained a part of old chart of Dagelet island (Ulleungdo) recently and I think many readers of this blog may be interested in it. It is a part of a British chart book which was published in 1798 , as there is a writing at the bottom of this sheet of charts that reads "Published as the Act directs Novr. 1st. 1798 by G.G.& J. Robinson Paternoster Row". This sheet of charts seems to be a copy of a French chart as it was all written in French. [Click the map to enlarge]

There is a chart of L'ile Dagelet (The Isle of Dagelet) in the sheet of charts and the French note says that "Discovered by the French frigates la Boussole and l'Astrolabe. The 27th May 1787. " with the exact location of the island. [Click the map to enlarge]
Another four charts depicted other islands - "a part of the isle of Quelpaert (Chejudo)", "the isle of Hoapinsu", "a part of the isle of Botol", and "the isle of Kumi". All of these islands were only "vue" (that means "seen"), not discovered. The dates depicted in these charts may illustrate how the French frigates navigated - they saw a part of the isle of Botol on 3rd May 1787, then the isle of Kumi on 5th May, the isle of Hoapinsu on 7th May, a part of the isle of Qeulpaert on 21st May and lastly they discovered Dagelet on 27th May.

"...May 27th I gave the signal that we arrived on the East Sea. After a short while, to the North~Northeast an island was observed that was not on any charts. This island seemed to be 20 leagues (actual 137kms) away from the Chosun coast. I tried to approach the island but it was difficult because the island was is the same direction as the winds. Fortunately, during the night the direction of the wind had changed. (May 28th) By dawn we left toward the island for measurements and I decided to name this island Dagelet after the astronomer Lapaute Dagelet among our crew who sighted it first. The circumference of the island is only three leagues (actual 33kms) Maintaining a distance of 1.9kms from the island we travelled almost all around but failed to find deep water. Therefore I decided to lower a small boat into the water and left Boutin in command to check the depths of water en route to land. He soon found that the depth of this place was 140 meters and it was about 200 meters from the island. The Northeast point of the island is 37° 25' North latitude and the 129° 2' East longitude. Even though the island is made of sheer cliffs, from the top to the shore it is covered with very beautiful trees. Other that seven little inlets for mooring the island is surrounded by precipitous cliffs. In this little inlet we observed some boats of Chinese style being built. It appeared that those boat builders were startled by our ship maybe because they were within the range of our cannons. They fled into the woods about 50 paces from their workplace. However, what we saw was a few huts, with no village or crops. It appeared that some Chosun carpenters from the mainland which is only 110 kms from Dagelet come with provisions and build boats during the summer before they take them to the mainland for sale. I'm sure this assumption is correct. When we returned to the West point of the island we again observed other workers building boats but they didn't see us approach because a point of land blocked their view. Those people by a tree stump looked frightened to see us except for a couple of them who didn't seemed to be afraid of us, they all ran into the woods. I thought we needed to persuade them that we are good people and are not their enemy so I looked for a place to drop anchor. Unfortunately the strong currents pushed us away from the island. Night approached. Due to our concerns that we might again be pushed from the island, and fears of not being able to retrieve the dispatched boat under Boutin's command I signalled to M. Boutin, who was about to land, and ordered him to return. I ordered the Astrolobe which was far to the West due to currents, to approach Mr Boutin's group. Luckily the high peaks of Dagelet blocked the winds and spend the night peacefully...."

TO Matsu-sama

From P243~251, is there any Argonaut island description? on P250 they wrote about "Lost her rudder"?
