Corsham took an early lead through Sam Ockwell but after Ali Bamford had smacked a right foot shot against the inside of the far post, he then hit a superb equaliser on forty minutes. This time, it was a left foot shot he nailed, leaving visiting keeper Chris Manns helpless.
In the second half, Aysa Corrick restored Town's lead on 67 minutes and despite some half chances to get back into the game, Oldland's finishing was disappointing with Manns rarely worked. Corrick added his second, and Corsham's third to seal the game although the O's pulled a goal back in stoppage time when a Corsham clearance rebounded off a defender and back into the net.
Two more tough games follow in the next seven days when the O's travel to Ashton & Backwell on Saturday before taking on Wells City in a crunch match next Tuesday evening.
