So now we can see that not only Germany and USA but also UK believed that Liancourt Rocks to be Japanese territory in the 1890's. The most developed countries in those days recognised that Liancourt Rocks didn't belong to Korea. This is another circumstantial evidence that Seokdo in the 1900 Korean Edict #41 could not have been Liancourt Rocks.
1894 British map of Japan and Korea
This map is from the "Popular Atlas of The World" which was published by G.W. Bacon & Co., Limited in London in 1894. The book of atlas contained fifty double page maps and this map is #36. The three islands can be seen in the Japan Sea - "Argonaut I.", "Dagelet I." and "Hornet Is.". Argonaut island was drawn in broken line, which may mean the presence of the island was doubtful. Dagelet island, today's Ulleungdo, was painted in red (pink) - the same colour as Oki islands and Izumo county. The most importantly, there is a red line drawn between Japan and Korea, which means the national border. As you can see, Argonaut island is in the Korean territory while Dagelet island and Hornet islands are in the Japanese territory.
