One of them happened to look up at the sky.

She gave a call to her sister to look also.

They both of them saw in the sky what looked like a siege going on.

They saw the different regiments with their colours, and recognised many of their friends among the Highlanders.
They saw Inverawe and his son fall, and other men whom they knew.
When they reached Inveraray they told all their friends of the vision they had just seen.

They also took down the names of those they had seen fall, and the time and date of the occurrence.
