'We had a very good day at Holbeach on Sunday, 9 or 10 souls found the Lord at night, some very interesting cases. Last night at Holbeach Hurn we had two come to seek the Lord and had a very good meeting - and I hope we shall have more tonight.'
'The Life of General William Booth', by Harold Begbie, Volume I, page 217-8.
Booth spent 18 months in the area and there are glimpses of a move of God from his letters. i suspect that there were many more salvations in Holbeach than those mentioned here.
I do not know where the meetings were held.
