Note the terrible proportion of sick in the raw divisions of Junot and Loison, as compared with the lower percentage in the old divisions of Ney’s and Reynier’s Corps.

Only Conroux’s division being with the main army, its 7,592 effective men alone have to be added to Masséna’s force, making a grand total of 54,116 for the available strength of the Marshal on Jan. 1, 1811.
On March 15th the total of 46,787 effectives in the old Army of Portugal had gone down to 44,407 (according to the return in the Paris Archives—Fririon says to only 40,751), though 1,862 drafts were brought up to the front by Foy on Feb. 5. This shows a shrinkage of 4,242 men effective since Jan. 1. But the loss in the sick is terrible—on Jan. 1 there were 18,873; on March 15 only about 6,000 (5,424 in the three army corps; no figures preserved for artillery, train, engineers, gendarmerie, &c.). Apparently multitudes must have perished in hospital during these eleven weeks.
Conroux’s division had about 6,400 effectives on March 15, which would make Masséna’s effective fighting force on that day 50,807. Claparéde’s division (at Guarda and Celorico) was on March 15 about 6,000 strong.
On April 1 the total of 44,407 effectives of the old army on March 15 had gone down to 39,905 present with the colours, not including Conroux and Claparéde.
On April 15 (the retreat having ended on April 5) the total of effectives was 39,546, not including Conroux and Claparéde.
The states of May 1 (Paris Archives) will be found under the Table ([No. XII]) entitled ‘The French Army at Fuentes de Oñoro.’
