Henley began the better of the two sides and opened the scoring in the fifth minute with a penalty from full-back Adam Lubbock.
The scores were levelled some five minutes later when Mark Chase converted a penalty goal attempt for Chinnor. Henley, dominating both ball and territory, began to seriously test the Chinnor defence in its own 22.
The dam finally burst when Henley’s Adam Lubbock touched down in the corner to give the visitors an 8-3 lead.
Henley continued to have the better of exchanges but could not convert any of it into points and so went in at half-time with an 8-6 lead.
Although Chinnor edged ahead in the 43rd minute with a converted try from the rumbustious Vickers, Chinnor coach Bowers decided that some changes in personnel were necessary and Sam Blewitt was replaced by Andrew Smith.
Chinnor switched the power on and the referee penalised Henley for collapsing the scrum.
On the third occasion this happened, the referee, Tom Davies, did not hesitate to run under the posts to award a penalty try to Chinnor.
As Mark Chase prepared to take the conversion, Ricky Hopwood, Matt Goode and Ian Stock came on for Chinnor. This immediately gave Chinnor greater pace and penetration with bullocking runs from Stock a particular feature of the rest of the night’s play.
Although the Henley decreased the gap to 18-11 with a penalty in the 64th minute, the Chinnor pack now began to dominate.
In the 67th minute a well executed Chinnor catch and drive saw Ed Rixon score Chinnor’s third try to give the home side a 23-11 lead.
Henley were not to be denied and in the dying minutes pressed the Chinnor line for hooker Ed Church to score in the corner.
