Salaat

Assalamualaikum Mufti Saab
At a public gathering 2 of us decided to make jamaat at salaah time,i was the imaam,by the end of the salaah 25-30 people had joined the jamaat.i am almost certain my wudhu broke during the salaah.i was not sure so i continued leading
Is there salaah accepted? (it was esha)
