On an extended business trip to Boston last week, I had occasion to take in the view from the top of the Prudential Tower. Here is a view of Boston today, looking seaward, with Dorchester Heights just visible next to the tall building toward the right of the image, jutting into the water. The small white monument just to the left of that building is at the top of the Heights.
It is hard to appreciate the strategic importance today, perhaps, in looking at the built-up nature of the city. Nonetheless, we see a view that neither Washington nor Howe could see in assessing their options.
