ST Sweeper was requisitioned in WW1 and returned 1919. I have standard information about it as well as the shipbuilder's model, but I do not have information about her wartime activities, except she was equiped as a minesweepr and anti-submarine work with a smooth bore bomb thrower howitzer.
She was returned to North Eastern Steam Fishing Company. Before WW2 she was sold to Norway, became Nordhavll, requisitioned by Norwegian Navy, came to UK fitted as a minesweeper and was torpedoed 10 May 1945.
I have some information about skippers, but nothing about actions. Can anyone help?

There are Ship's Logs for SWEEPER at Kew Archives,they run from Aug 1915 (ADM53/61957) through consecutive periods and file numbers to ADM53/61985 (Feb 1919).
Sounds to me like a good day out to read them all !

Hi.

I’m sure I’ve read about her paired at the time with another requisitioned Grimsby trawler that was sunk by a mine but I cannot find the the source at present!

You probably have these and other details of her in the Second W.W.
but none of my sources link her with North Eastern Steam Fishing Company

S.T. SWEEPER GY 853 Built for South Western S. F. Co. Ltd. Grimsby
Aug. 1914 -1919 Admiralty No. 54 Sold to Thomas W Bascomb in 1915.
1935 to Boston Deep Sea F. Co. Ltd. Grimsby.
Mar.1936 to Norway

Cheers, Terry

The ships logs should record her activities day by day, with a side dedicated to each day.
