Shortly before dark the move was made, the women and children were crowded into the few vehicles available, and accompanied by the men, some on foot and some on horseback, they got away by the road leading towards Umballa.

They were only just in time, for before the last of the party were out of sight of the cantonment, crowds of Natives poured into it, burning, plundering, and destroying everything they could find.
Amongst the fugitives from Delhi was Captain Tytler, of the 38th Native Infantry, who, after a variety of vicissitudes, reached Umballa safely with his wife and children.

When Anson's force was being formed for the advance on Delhi, Tytler was placed in charge of the military treasure chest, and through some unaccountable negligence Mrs.Tytler was allowed to accompany him.

I believe that, when Mrs.Tytler's presence became known to the authorities, she would have been sent out of camp to some safe place, but at that time she was not in a fit state to travel, and on the 21st June, a few days after the force took up its position under a heavy cannonade, she gave birth to a son in the waggon in which she was accommodated.

The infant, who was christened Stanley Delhi Force, seems to have been looked upon by the soldiery with quite a superstitious feeling, for the father tells us that soon after its birth he overheard a soldier say; 'Now we shall get our reinforcements; this camp was formed to avenge the blood of innocents, and the first reinforcement sent to us is a new-born infant.' Reinforcements did actually arrive the next day.
It was on the afternoon of the 8th June that the British force was placed in position on the Ridge.
