General Mitre became commander-in-chief of the combined armies for the invasion of Paraguay and was absent for several years in the field.
He is thus commander-in-chief, as also governor-designate for time of war, but his authority does not extend to ships belonging to organized squadrons or divisions.
He was made commander-in-chief of both the military and naval forces with supreme authority, and in his hands was placed the final appointment to all political and judicial posts and to vacant city magistracies.
In 1855 he was appointed commander-in-chief of the Russian forces in the Crimea in place of Prince Menshikov.
As commander-in-chief, he summons the princes to the council and leads the army in battle.
