I.e., outside the city, defending the trench.
Yathrib was the name of Medina before the arrival of the Prophet (ﷺ) and Muslim emigrants.
All the fighting men of Madinah had come out of the city and camped in the open space between the City and the Trench that had been dug all round. The disaffected Hypocrites sowed defeatist rumours and pretended to withdraw for the defence of their homes, though their homes were not exposed, and were fully covered by the vigilant defensive force inside the Trench.
