§ 238. In case the contrary is not stipulated, an armistice commences the very moment the agreement upon it is complete. But often the parties stipulate in the agreement the time from which the armistice shall begin. If this is done in so detailed a manner that the very hour of the commencement is mentioned, no cause for controversy is given. But sometimes the parties fix only the date by stipulating that the armistice shall last from one certain day to another, _e.g._ from June 15 to July 15. In such case the actual commencement is controversial. Most publicists maintain that in such case the armistice begins at 12 o'clock of the night between the 14th and the 15th of June, but Grotius (III. c. 21, § 4) maintains that it begins at 12 o'clock of the night between the 15th and the 16th of June.[459] Therefore, to avoid difficulties, agreements concerning armistices ought always to stipulate whether the first day is to be included in the armistice. Be that as it may, when the forces included in an armistice are dispersed over a very large area, the parties very often stipulate different dates of commencement for the different parts of the front, because it is not possible to announce the armistice at once to all the forces included. Thus, for instance, article 1 of the general armistice at the end of the Franco-German War[460] stipulated its immediate commencement for the forces in and around Paris, but that with regard to the other forces its commencement should be delayed three days. Article 38 of the Hague Regulations enacts that an armistice must be notified officially and in good time to the competent authorities and the troops, and that hostilities are suspended immediately after the ratification or at a fixed date, as the case may be. [Footnote 459: See Pradier-Fodéré, VII. No. 2897. The controversy occurs again with regard to the end of an armistice; see below, § 240.] [Footnote 460: Martens, _N.R.G._ XIX. p. 626.] It sometimes happens that hostilities are carried on after the commencement of an armistice by forces which did not know of its commencement. In such cases the _status quo_ at the date of the commencement of armistice has to be re-established so far as possible, prisoners made and enemy vessels seized being liberated, capitulations annulled, places occupied evacuated, and the like; but the parties may, of course, stipulate the contrary.
