In Slavery in Massachusetts, Thoreau writes:
The events of the past month teach me to distrust Fame. I see that she does not finely discriminate, but coarsely hurrahs. She considers not the simple heroism of an action, but only as it is connected with its apparent consequences. She praises till she is hoarse the easy exploit of the Boston tea party, but will be comparatively silent about the braver and more disinterestedly heroic attack on the Boston Court-House, simply because it was unsuccessful!
To what heroic attack on the Boston Court-House does the author allude? The case of rescuing Shadrah Minkins was successful, may it be that Thoreau alludes to another case?
