In the French army of 1799, there were four battalions of sappers, consisting of 120 officers and 7,092 men. In 1804, Napoleon organized five battalions of these troops, consisting of 165 officers and 8,865 men. Even this number was found insufficient in his campaigns in Germany and Spain, and he was obliged to organize an additional number of sappers from the Italian and French auxiliaries. The pioneers were then partly attached to other branches of the service. There is, at present, in the French army a considerable number of sappers or pioneers detached for the service of the infantry regiments, three companies of _sapeurs-conducteurs_, and forty-two companies of _sapeurs_. In the French army of 1799, there were six companies of miners, consisting of 24 officers and 576 men. In 1804, Napoleon increased these troops to nine companies, containing 36 officers and 864 men. The present French peace establishment contains six companies of miners, organized much the same as under Napoleon. In the French army of 1799 there were two regiments of pontoniers, of 38 officers and 960 men. But this number was found too small in the remaining campaigns, and the deficiency was temporarily supplied by organizing sailors for these duties. In the present French army organization, there are eleven companies of pontoniers, forming a regiment of sixty-three officers. _We have in our service no sappers, miners, or pontoniers_, and, in case of war, would be found without the means of executing any military works, or performing any military operation which would require engineer troops.
