new lands that he had conquered, and in the rebellious lands that he had re-conquered. In 82, he sailed to either Kintyre or the shores of Argyll, or to both. In 83 and 84, he moved north along Scotland's eastern and northern coasts using both land and naval forces, campaigning successfully against the inhabitants and winning a significant victory over the northern British peoples led by Calgacus at the Battle of Mons Graupius. Archaeology has shown the Romans built military camps in the north along Gask Ridge, controlling the glens that provided access to and from the Scottish Highlands, and also throughout the Scottish Lowlands in northeastern Scotland. Agricola built a network of military roads and forts to secure the Roman occupation. Existing forts were strengthened and new ones planted in northeastern Scotland along the Highland Line, consolidating control of the glens that provided access to and from the Scottish Highlands. The line of military communication and supply along southeastern Scotland and northeastern England (i.e., Dere Street) was well-fortified. In southernmost Caledonia, the lands of the Selgovae (approximating to modern Dumfriesshire and the Stewartry of Kirkcudbright) were heavily planted with forts, not only establishing effective control there, but also completing a military enclosure of south-central Scotland (most of the Southern Uplands, Teviotdale, and western Tweeddale). In contrast to Roman actions against the Selgovae, the territories of the Novantae, Damnonii, and Votadini were not planted with forts, and there is nothing to indicate that the Romans were at war with them. Agricola was recalled to Rome in 84. Findings In 2019, GUARD Archaeology team led by Iraia Arabaolaza uncovered a marching camp dating to the 1st century AD, used by Roman legions during the invasion of Roman general Agricola. According to Arabaolaza, the fire pits were split 30 metres apart into two parallel lines. The findings also included clay-domed ovens and 26 fire pits dated to between AD 77 and 86 and AD 90 loaded with burn and charcoal contents. Archaeologists suggested that this site had been chosen as a strategic location for the Roman conquest of Ayrshire. AD 84–117 Agricola's successors are not named in any surviving source, but it seems they were unable or unwilling to further subdue the far north. The fortress at Inchtuthil was dismantled before its completion and the other fortifications of the Gask Ridge in Perthshire, erected to consolidate the Roman presence in Scotland in
