What Was That?

Yesterday morning, I went outside at about 5:30 to get some firewood, and there were six flying objects coming in my direction in formation.  One was a well lit large looking plane, while the other five had single red beacon lights.  Two were flying on the left flank of the well-lit plane, and the other three were hanging back a few hundred yards.  I don't know if the five were escorting fighters or drones or something, but they seemed to be flying fairly slowly.  If they were scanning their surroundings for activity, they saw me taking a leak.
