Lahore was crowded with the families of European soldiers, and with ladies who had come there from various parts of the Punjab, all in terrible anxiety as to what might be the ultimate fate of their husbands and relatives; some of whom were with Native regiments, whose loyalty was more than doubtful; some with the Movable Column, the destination of which was uncertain; while others were already on their way to join the army hurrying to Delhi.
The difficulty with Campbell having been settled, Chamberlain assumed the command of the Movable Column, the advent of which on the 2nd June was hailed with delight by all the Europeans at Lahore.

A regiment of British Infantry and two batteries of Artillery afforded a much needed support to the handful of British soldiers keeping guard over the great capital of the Punjab, and gave confidence to the Sikhs and others disposed to be loyal, but who were doubtful as to the wisdom of siding with us.
The disturbing element was the Native troops which accompanied the column.

They had not shown openly that they contemplated mutiny, but we knew that they were not to be trusted, and were only watching for an opportunity to break out and escape to Delhi with their arms.
I was living with the Brigadier in a house only a few minutes' walk from the garden where the Native regiments were encamped, and the spies we were employing to watch them had orders to come to me whenever anything suspicious should occur.

During the night of the 8th June one of these men awoke me with the news that the 35th Native Infantry intended to revolt at daybreak, and that some of them had already loaded their muskets.

I awoke the Brigadier, who directed me to go at once to the British officers of the regiment, tell them what we had heard, and that he would be with them shortly.
