Active army (with colors) 289,910 Reserve (including men of first and second categories) 638,979 Mobile militia 299,596 Territorial militia 1,889,659 _________ Total war strength 3,159,836 According to a calculation, which need not be given in detail here, the above number of total men available includes upward of 1,200,000 fully trained soldiers, who have been through the ranks, with perhaps another 800,000 partially trained men of the second category, the remaining million being completely untrained men, who have passed all their nineteen years of obligatory service in the third category. The organization for putting the above numbers of men into the field is as follows: The fully trained men are organized in four armies, each army consisting of three corps, one cavalry division, and a number of troops for the lines of communication. The twelve corps are recruited and organized on a territorial basis, each corps having its allotted area, as shown in the sketch, which also indicates the locality of corps headquarters. The Italian army corps, which is larger than that in other European armies, is composed of two active army divisions, with thirty guns each, one mobile militia division, brought up to strength from the territorial militia, one regiment of Bersaglieri, or light infantry, one cavalry regiment, one field artillery regiment of six batteries, (corps artillery,) and other technical and administrative units. The strength of the corps amounts to 50,000 men, with 8,400 horses and 126 guns, and this gives each of the four armies a strength of 150,000 men, 25,200 horses, and 378 guns, with the addition of a cavalry division of 4,200 sabres. The first line Italian army, therefore, which can be put into the field seven days after mobilization is ordered amounts to 600,000 men, 100,800 horses, 1,512 guns, and 16,200 sabres. But these cadres only absorb half the fully trained men called out on mobilization; duplicate corps will consequently be formed to take the place of the twelve first-line corps as soon as they have been dispatched to their concentration rendezvous. It is believed that sufficient guns have now been provided for these twelve duplicate corps, but it is unlikely that more than two cavalry divisions could be formed in addition to the four divisions with the first-line armies. These duplicate corps would be ready to take the field three or four weeks after the concentration of the first twelve corps. The above calculations show that within a few weeks after the declaration of war Italy can place in the field a force of 1,200,000 men, (24 corps,) and would still have 1,800,000 men of fighting age left at the depots after the field armies had been dispatched to the front.
