Tidswell was a native of Brierfield, Lancashire.

The citation for the Distinguished Conduct Medal published in the London Gazette reads, "When this NCO's platoon was held up by a strong machine gun post he went forward alone, reconnoitered the post, came back and directed his platoon to the flank, then personally rushed the post in front to cause a diversion, and so allowed the platoon to dash in and capture over 30 of the enemy. His conduct in this case and on previous occasions set a splendid example to the men of his platoon".

His Military Medal was awarded, 'For gallantry on the night of 21 - 22 October 1917, Corporal Tidswell crossed and re-crossed No Man's Land, again and again, bringing in wounded, and directed his team towards positions where other men lay. His endeavours went far to reduce the casualty list, many would have perished before morning but for his efforts.
