"By this stage first [Schmid] and second [Poland's Kuba Giermaziak] had got away and it took another three-four laps for Earl to catch them.
"Fortunately they were in a real tussle, which slowed them down just enough for Earl to catch them."
Tait said at this point, Giermaziak let Schmid go and focused on defending his second place spot from the New Zealander.
"He successfully did this for about five laps. Earl tried very hard and a number of times got alongside but couldn't make it past.
"Some very exciting racing - the international TV coverage spent a huge amount of time focused on Earl, as this was where the action was.
"A lot of the race coverage was from Earl's in-car camera."
Bamber's third placing at Silverstone has him on 53 points, sitting second behind Giermaziak in the overall standings.
"That was a great race and I'm very happy with the overall outcome," he said.
Next round of the Supercup is at Germany's Hockenheimring Baden-Wrttemberg, July 18-20.
