From Mirande the army had a march of only eleven miles to reach the next halt, Seissan on the river Gers. Baker refers to the army marching near the mountains of ‘Aragon’, the Pyrenees, for this and the three following days, and describes the passage to Seissan on Friday 23 October as ‘difficult, hard and mountainous’. Today's roads cannot be said to be difficult and to describe the countryside as mountainous is an exaggeration. However, anyone on foot would sympathise with Baker's overall judgement that it was a hard day's march. Indeed, the next two days were going to be hard going, with eight rivers running north from the Pyrenees to flow into the river Garonne to be crossed in a distance of a little over twenty miles. The route first crosses the river Grande Baïse with a steep climb of 300 feet up the escarpment on the eastern side, then down a gentle, almost imperceptible descent to the Petite Baïse. The same pattern is repeated, with a steep climb before descending gently to the Sousson, up again and then down into the valley of the Cédon, before a final, slightly lower, escarpment, and the last descent of the day into the Gers valley and the town of Seissan.
