Rennes, the ancient capital of Brittany, is the head-quarters of the 10th Army Corps, and the site of a large arsenal in addition to the barracks, while it is the military centre for the departments of Côtes-du-Nord, Manche, and Ille-et-Vilaine. In the early part of the eighteenth century the town was almost destroyed by fire, a catastrophe that is not even yet forgotten; while as the birthplace of Boulanger, who introduced many reforms into the French Army and was largely responsible for its efficiency in recent years, Rennes is peculiarly connected with military matters. It may be remembered, by the way, that the second Dreyfus trial was held here in 1899. The population of the town is about 75,000, and it is 51 miles south-east of St. Malo and 232 miles west-south-west of Paris. Historically, Rennes was the centre of several Roman roads which are still recognisable, and in mediæval times it suffered greatly from the wars between French and English. In the revolutionary period the Republican Army made Rennes their centre for the operations against the Vendeans, but it has no later prominence in connection with military history. Rouen, 87 miles north-west of Paris by rail, is the head-quarters of the 3rd Army Corps, is the ancient capital of Normandy, and military centre for the departments of Calvados, Eure, Seine-Inférieure, and parts of Seine-et-Oise and of Seine. It has a population of about 120,000, including the garrison, and is a town of narrow, picturesque streets and of old-world dignity and interest. Here William the Conqueror died and Jeanne d'Arc was burned--a statue commemorates the latter event in the town. Although 78 miles from the sea, Rouen is one of the principal French ports, the bed of the Seine having been deepened from the sea to the city by an ingenious system of embankments, which forced the river to deepen its own bed rather than extend its width--and military labour went far toward the construction of the embankments. Toulouse, the head-quarters of the 17th Army Corps, is the military centre for the departments of Ariege, Haute-Garonne, Gers, Lot, Lot-et-Garonne, and Tarn-et-Garonne. The town is peculiarly liable to great floods, and those of 1855, which swept away the suspension bridge of St. Pierre, and of 1875, which destroyed 7000 houses and drowned 300 people, are still remembered in the city. It is situated 478 miles south of Paris and 160 miles south-east from Bordeaux, and, with a population of about 150,000, ranks as the metropolis of Southern France.
