In my project to reproduce at 1:1 ratio (at least) a Piedmontese Brigade for my scenario, I went through the problem to understand how was the organization of a Piedmontese Infantry Regiment in 1848 at war.
Each Line Brigade, which had the name of the recruiting district (a fashion that lasted untill 2WW in the Italian Army) was composed of 2 Line Regiments.
Every Regiment had - after a lot of changes in the previous years - the following composition:
The theoretical force was of 2768 men, but no unit ever reached this numbers.
Every Regiment had a General Staff of 23 officers with additional 62 men; all battalions were on 4 companies, as detailled in the scheme, with the composition of men described.
The Battalion staff numbered 15, and each company 225 men.
Problem was to understand how a company was composed. In fact 200 men (as average) is a quite huge number as basic component. For this purpose I did not find any source; after long researches I found on the super detailled book "L'Armata Sarda e le Riforme Albertine" , published by the Stato Maggiore dell'Esercito Italiano, this picture (for a regiment in 1834)
It is possible to note that a company was on 6 pelotons, that should have a force of around 30 men, a number long preserved in the Italian Army.
It is also to suppose that each pelon was under the orders of the 2 Second Lieutenant and of 4 NCO. This was still the structure of a Company when I was in the Army, when as Second Lieutenant I commanded 1 peloton of around 20 men (divided in squads). Inside the peloton, under the direct command of the commanders of pelotons there were the Corporals.
As a fighting force - considering that my scenario would be in May 1848, hence after almost 2 months of war - I will downscale every company from 220 (theoretical), to a real 200 men in March 1848 to a loss of around 10% (sick, deserters etc.) to 185 men per company so 30 or 31 men per peloton.
