In the years 82 to 85, the Romans under Gnaeus Julius Agricola launched a campaign against the Caledonians in modern Scotland. In this context the Roman navy significantly escalated activities on the eastern Scottish coast. Simultaneously multiple expeditions and reconnaissance trips were launched. During these the Romans would capture the Orkney Islands ("Orcades") for a short period of time and obtained information about the Shetland Islands. There is some speculation about a Roman landing in Ireland, based on Tacitus reports about Agricola contemplating the island's conquest, but no conclusive evidence to support this theory has been found.
