Both sides came into this contest with contrasting form with Bohs unbeaten in their opening two games and Derry looking for their first point of the campaign after two defeats from two.
Kenny Shiels has a seriously impressive record with his side in Dalymount in recent times and Tuesday’s win means Derry have now won the last eight fixtures between the sides at the Dublin venue.
It was a quiet first half with both sides taking their time to get to grips with the snowy surfaces and ice cold temperatures
Ronan Curtis and Eoghan Stokes exchanged chances in the opening half but the game remained scoreless heading for the break.
The only goal of the game went the way of the Candystripes and fell to striker Ronan Curtis to tuck the ball away after a scramble in the box following a corner and put Derry City 1-0 to the good.
The Gypsies tried their very best to get back into the game but it was just one of those nights and as they pushed forward to get back into the game they had a goal ruled out for offside and then in the closing stages had a penalty saved by man of the match Ger Doherty.
