Normally summaries are given at the beginning or end of someone’s reign; here it is given in the middle. We find a summary at the end of 1 Samuel 14 because the focus in chapters 15 and onward will be on David rather than Saul. Saul’s time as king has not come to an end. He will continue to rule for a few more years. But during that time and for the remainder of the book, he moves from centre stage to serving as a foil to David.
47 Après que Saül eut pris possession de la royauté sur Israël, il fit de tous côtés la guerre à tous ses ennemis, à Moab, aux enfants d'Ammon, à Edom, aux rois de Tsoba, et aux Philistins; et partout où il se tournait, il était vainqueur.
