First post in a long while, but I couldn't miss this.
The Boston Globe has a nice write-up of the Boston Public Library's "We are One" exhibition that features 4 watercolors painted by Lt. Richard Williams of the British Army during the Siege of Boston. One of the paintings shows Fort Hill, including the meeting house (First Church in Eliot Square) and "Rebel Lines."
The website has a zoomable version of the painting, but you should really go down to the BPL to check it out for yourself if you can.
Here's the full info, cribbed from the BPL site:
