with one accord

It was startlingly like the image conveyed to me in Dr. Seward’s diary of the opening of Miss Westenra’s tomb; I fancy that the same idea seemed to strike the others, for with one accord they shrank back.

“When the shades of evening had reached a certain degree of density, suddenly the whole drove with one accord rose from the road and sought a perch in the neighboring trees,” Smith wrote.

With one accord the girls moved warily towards the window.

They decided with one accord, without even a whisper, to creep up to it so silently that even the members of their own army, who might already be waiting there, would not know of their arrival.

No one doubted that the tribe would be found at the Castle Rock and when they came in sight of it they stopped with one accord.
