At 3.50am on 31 July 1917 the attack commenced.

Most of those guards were killed when the attack commenced.

It must have waited out of range until the attack commenced.

The attack would commence during the early hours of 9 or 10 March.

I expect the attack to commence in thirteen point two minutes.

The attack commenced as planned, five minutes ahead of the two other raids at 19.25 hours.

One last key was needed before the attack could commence.

They did not agree on what the combined army's strategy should be when the attack commenced.

The attacks commenced at 12 midnight local time and the website has been down for over 2 days.

The attack commenced early morning on 1 February and by 1600 both objectives had been secured.
