Guernsey head coach Jordan Reynolds says his side's 20-18 win over relegation rivals Amersham and Chiltern at Footes Lane was "brilliant".
Guernsey recorded back-to-back wins for the first time this season as they moved up a place to 12th in the National Three London table.
"It was do or die for us really," Reynolds told BBC Radio Guernsey.
"There was a lot of pressure on us to win that game, so to get that win was brilliant."

Guernsey needed to win after rivals Tring, who were bottom of the table going into the weekend, surprisingly beat fifth-placed Chichester to move off the bottom.
"The guys deserved it but Amersham were playing at 100% for the entire game, we were about 40%," Reynolds added.
"If we could have risen that to about 60% we could have made it easier for ourselves, but we got the win and that's all the counts.
"I don't think there was a minute in that second half when we weren't in control and I think that was the difference."
Reynolds' side beat Amersham in November, but had the after playing a suspended player.
