Origins and creation
In 1806 Napoleon decided to expand Guard infantry without immediately diluting Old Guard criteria. In the same movement as the fusilier-grenadiers arose the fusilier-chasseurs: twin formations that constitute, in historians’ language, the Middle Guard.
The project answered a strategic reality. After Austerlitz and before Jena, the Empire needed a quality reserve, recruited among good line soldiers, yet without requiring the ten years’ service and stature of the foot grenadiers.
For the soldier, entering the fusilier-chasseurs already meant crossing the Guard’s threshold: higher pay, prestige, and the prospect of serving near the Emperor. For the enemy, it was a mass of elite infantry recognisable by uniform and discipline.
Organisation and strength
The fusilier-chasseurs were organised in regiment and battalions on the Guard infantry model. Their strengths remained well below the Young Guard masses created after 1809-1813, yet sufficed to form a credible operational reserve.
Guard infantry generals — Curial, Roguet and others by period — appear in command of these formations. Marshal Mortier often commanded ensembles that encompassed them; Napoleon himself decided the moment of commitment.
In the Old / Middle / Young Guard tripartition their place was central: too recent for the strict Old Guard, too selected to be confused with Young Guard tirailleurs.
Uniform, arms and recruitment
The fusilier-chasseur uniform approached that of the Guard while distinguishing itself from the grognards: shako rather than bearskin for much of the period, Middle Guard distinctives. Arms remained the regulation infantry musket.
Recruitment drew from line regiments among men of good conduct and suitable stature, with seniority below that required for the Old Guard. Promotion into the fusilier-chasseurs was already an envied reward.
Training aimed at volley fire, column manoeuvre and defensive solidity. From 1813 the pressure of losses sometimes accelerated incorporations, without entirely erasing corps identity.
Deeds of arms
From their creation the fusilier-chasseurs followed the Grande Armée in Prussia and Poland. In 1809, during the Austrian campaign, Guard infantry was more heavily engaged than in the Empire’s early years: Essling then Wagram saw the reserve brought closer to the fire.
At Wagram (5-6 July 1809) the Middle Guard helped consolidate victory after the trials on the Danube. In Russia, at Borodino (7 September 1812), Middle Guard elements remained in the reserve deployment Napoleon long husbanded.
The 1812 retreat and the 1813-1814 campaigns decimated cadres and soldiers. On 18 June 1815 at Waterloo it was mainly Middle Guard formations — fusiliers and equivalents under the Hundred Days organisation — that mounted the final assault on the Allied centre.
The failure of that attack, under fire from British squares and with the Prussian arrival, marked the Empire’s military end. Modern historiography stresses the Middle Guard’s role in that assault, often wrongly amalgamated with the Old Guard alone.
Legacy and memory
The fusilier-chasseurs, like their fusilier-grenadier brothers, suffer relative popular oblivion beside the bearskinned grognards. Yet without this Middle Guard the Napoleonic reserve system would not have sustained the widening of wars after 1806.
Waterloo paradoxically fixed their memory: it was this intermediate reserve, more than the Old Guard squares at dusk, that carried the Emperor’s final infantry offensive.
