14 bright lights flying in trail

I had stepped out on to my back deck at 0530 to smoke a cigarette, when I observed what at first I believed to be the ISS traveling from the NW to the SE in the pre-dawn sky.
I then noticed another object of the same size and speed, in trail, of the first object and thought it must be a resupply module chasing the ISS in preparation for a rendezvous.
I was somewhat startled to observe yet a third object trailing the first two, as I have never seen three satellite-like objects trail each other before.
The roof of my house was obscuring the view to the NW, so I stepped farther out onto my deck and was shocked to see even more of these objects in trail of each other.
Total of 14 objects, no sound, at satellite altitude, appeared to be satellites in trail.
The first 6 or 7 seemed to be at an equal distance from each other, and the last 7 seemed to be somewhat staggered.
These objects where just pinpoints of bright light, no navigation lighting observed, and moved across the sky at the constant speed of a satellite. I believe these objects were in orbit, and not high flying aircraft.
I observed a total of 14 objects, but there may have been more before I went out on my deck.
