This was a delicate task, since some client kingdoms were more important, strategically, than others. While there was no chance of the Cantians affecting the outcome of the current campaign, the Icenians - a large and war-like tribe - bordered the right flank of the Roman advance, and needed to be treated with careful respect, until sufficient force could be brought to bear on them and put them in their place. Further north, much further north, lay the kingdom of the Brigantians, ruled by Cartimandua, a young queen of formidable will, who had decided that there was more to be gained from appeasing rather than opposing Rome. For now at least. But in time, these client kingdoms would be remorselessly drawn into the Empire and subjected to its rule. The presence of a legion camped on their doorstep was usually enough to quell any temptation to rebel against the new order. And if they did resist then they would be taught a swift and bloody lesson in the realities of the new order. The dispatching of Hosidius Geta’s column to the east was merely the first step in adding the lands of the Icenians to the new province.

Meanwhile General Plautius would take the Twentieth and the Fourteenth legions, and most of the auxiliary cohorts and push forward north of the Tamesis to establish the other end of the new province’s frontier, and begin the task of constructing military roads to link up the forces dispersing across the width of the island.

The third column, under Vespasian, consisted of his legion, the Second, four cohorts of Batavian horse, two cohorts of Batavian infantry and two large mixed units of Illyrians. General Plautius had also promised his legate use of the British fleet based at Gesoriacum in Gaul, as soon as Vespasian had finished off Caratacus and could move on to subdue the remaining southern tribes still intent on defying Rome. But Caratacus had gone to ground and Vespasian was consumed with frustration at the prospect of digging the wily British commander out of his hole. It was already late summer and soon the leaves would begin to brown and fall. There would be plenty of rain and the native tracks would turn into glutinous rivers of mud that would slow down the heavy wagons of the baggage train to an exhausting and filthy crawl. Removing the threat of Caratacus might be the last operation Vespasian would be able to carry out before the campaigning season came to an end.
