An armistice is not a partial or a temporary peace; it is only the suspension of military operations to the extent agreed upon by the parties.
143
When an armistice is concluded between a fortified place and the army besieging it, it is agreed by all the authorities on this subject that the besieger must cease all extension, perfection, or advance of his attacking works as much so as from attacks by main force.
But as there is a difference of opinion among martial jurists, whether the besieged have the right to repair breaches or to erect new works of defense within the place during an armistice, this point should be determined by express agreement between the parties.
144
So soon as a capitulation is signed, the capitulator has no right to demolish, destroy, or injure the works, arms, stores, or ammunition, in his possession, during the time which elapses between the signing and the execution of the capitulation, unless otherwise stipulated in the same.
145
When an armistice is clearly broken by one of the parties, the other party is released from all obligation to observe it.
146
Prisoners taken in the act of breaking an armistice must be treated as prisoners of war, the officer alone being responsible who gives the order for such a violation of an armistice. The highest authority of the belligerent aggrieved may demand redress for the infraction of an armistice.
