They had an hour to go before the first light of dawn.

But before the light of dawn, we were upon our way.

The first light of dawn was already strong in the east, but they had made good enough time.

He was up and away with the first light of dawn.

But he was up before the first light of dawn.

Three hours to go to the first light of dawn.

But in the morning with the light of dawn everything would change.

We leave with the dawn light in three days' time.

The sun was not up yet, but the first dawn light had come.

It doesn't look too good in the cold light of dawn.
