Were his disciples with him?

Matthew and Mark: “And straightway Jesus constrained his disciples to get into a ship, and to go before him unto the other side, while he sent the multitude away. And when he had sent the multitudes away, he went up into a mountain apart to pray; and when the evening was come, he was there alone. But the ship was now in the midst of the sea” (Matt. xiv, 22–24; Mark vi, 45–47).

Luke: “And it came to pass, as he was alone praying, his disciples were with him” (ix, 18).

Matthew and Mark send his disciples ahead in a ship to make room for his miracle of walking on the sea, a miracle that Luke knows nothing of.
