'He [Mr Stansfeld] did however resign over the Mazzini business'
'Towards the end of Feb 1864, four Italians were brought to trial in Paris on a charge of attempting to assassinate Napoleon III'
Mazzini was attacked as the instigator of the plot and Stansfeld was involved as a friend of Mazzinis and the fact that Mazzini and his friends had made use of his house for letters
Stansfeld at once offered to resign but Palmerston refused to allow this
Finally however owing to further attacks and innuendoes Stansfeld on Apr 4 sent his resignation to Palmerston
For details of this see Life of James Stansfeld by J Hammond and Barbara Hammond 1932, ch 5
At Stansfeld's death in 1898 Lady Stansfeld asked JB if she would write his life 'but Mrs Butler felt she could not undertake it'
An authoritative life was not written till 1932 of him by the Hammonds (see above)
