(4) Cavalry Division Margaron:-- 1st Provisional Chasseurs 263 3rd ” Dragoons 640 4th ” ” 589 5th ” ” 659 Squadron of volunteer cavalry 100 ----- 2,251 (5) Artillerymen for 23 guns, engineers, train, & 700 ------ 15,656 But from this 15,656 large deductions have to be made; each of the eleven line battalions present had given its grenadier company to contribute to the four battalions of ‘Reserve Grenadiers’ which Junot had formed. We must therefore deduct from them about 1,350 bayonets. Delaborde had lost 600 men at Roliça. Loison’s regiments had been thinned by the dépôt battalion left to garrison Almeida, and by his losses in his campaign on the Douro and in the Alemtejo. Thiébault states that the casualties had amounted to 450 during these operations: the details left at Almeida, including many sick, were 1,000 strong, so we must subtract 1,450 from Loison’s total. This is liberal, as some, both of the Almeida force and of the Alemtejo losses, came from regiments not present at Vimiero (e.g. the 1st Hanoverians and the 4th Swiss). We must make some deduction for the ordinary hospital wastage of the troops which had come out of Lisbon with Delaborde and Junot, seven battalions and two regiments of cavalry. Loison’s sick are already partly accounted for by the Almeida details. It would seem that 1,000 would be an ample allowance. When the French evacuated Portugal they had 3,281 men in hospital. Of these, 1,200 were the wounded of Vimiero. Of the remainder, 1,000 may have belonged to the ten and two-thirds battalions present at the battle, the other 1,081 to the eleven and one-third not present. For the infantry then we allow-- 12,705 of original strength, minus 1,350 Grenadiers, 600 lost at Roliça, and 1,450 in garrison at Almeida or lost in the insurrection, and 1,000 sick (4,400 in all) 8,305 Add for four battalions of Reserve Grenadiers 2,100 ------ Total 10,405
