On 20 December massive columns of workers were entering the city.

Nimeiry and his government were narrowly saved after a column of army tanks entered the city.

As the column entered the parade ground it formed ranks.

At 10:30 on 11 June, the column entered British lines.

Two other columns had already entered the city and were approaching the palace together.

If no columns can enter the basis and the solution to the relaxation is not integer, then branching occurs.

The Aiel commander had left a few men where they could signal a warning just before the column entered the killing ground.

The southernmost outpost notified him that their column had entered the valley and was moving briskly.

"An armored column is entering the valley," he said into his headset.

The column entered the town at 1600, its tanks firing the occasional shot.
