Gloucester Rugby Academy duo Ollie Thorley and Sam Underhill were both involved as the England U18 side secured the second win of their tour of South Africa.
Fresh from their exploits in the Gloucester side that lifted the Premiership Rugby 7s, Thorley started the game on the left wing, while Underhill was named amongst the replacements.
The victory means England are two wins from two games in South Africa after beating France 23-6 in George.
Under the imposing gaze of the Outeniqua Mountains, Joe Marchant's intercept try when the game was on a knife-edge at 9-6 swung the game into England's favour and John Williams' late try on debut sealed the win.
Fly half Theo Brophy Clews added both conversions as well as two crucial earlier penalties, while Rory Jennings scored one three-pointer.
It wasn't all plain sailing for England as France more than held their own in an even first half. But after going in 6-6 at the break, the second period belonged to England who pulled away towards the end.
Head Coach John Fletcher said:
"It was another tough game, as it always is when you play France. I thought that we dominated the game for periods, but France defended and tackled well, and to be fair they had a long spell in our half.
"We made a few too many unforced errors, particularly early on in the game. But I thought that we were quite comfortable throughout and we've come through with each player on tour having had a start which will start us in good stead for Saturday's game against South Africa.
"We know what South Africa will bring - they mirror the Seniors. They'll be big and physical, which is what we expect, we'll have to up our game and put in a big performance, which I know we are capable of."

It's the first Gloucester-Bristol derby at Kingsholm in over eight years this Saturday (kick off 4:30pm) and, previewing the game with the local media this week, Defence Coach Jonny Bell stressed that, with both teams in the bottom half of the table, they both need the points.
Speaking to the local media this week, Gloucester front rower John Afoa knows the challenge ahead this week against Bristol, and calls on the Cherry and Whites to make the most of home advantage as a determined squad look to bounce back from a narrow loss to Saracens.
Tom Savage speaks to GRTV and the local media as Gloucester went down by 24-20 at Saracens on Sunday afternoon. The second row was disappointed with the result, despite a strong showing from the hosts.
Speaking immediately after the game, skipper Willi Heinz thought that Gloucester had executed their game plan reasonably well and competed hard against Saracens. However, it wasn't enough but the squad will have plenty to work on this week ahead of the derby match against Bristol.
Gloucester may be coming off their best win of the season, the 38-16 victory over Wasps last weekend, but Director of Rugby David Humphreys admits that Sunday's trip to Saracens is an even tougher test.
After a series of contract announcements last week, hooker Richard Hibbard is the latest Gloucester Rugby player to commit to a new contract at the club and told GRTV how much he enjoys playing in the Cherry and White of Gloucester.
A try scorer in the 36-18 Aviva Premiership win over Wasps at Kingsholm on Saturday, Charlie Sharples admitted that Gloucester would enjoy the moment but can't get too carried away. The team got what they deserved but the winger wants these performances to be more frequent.
England Head Coach Eddie Jones has made two changes to his side to play Australia in Saturday's final match of the Old Mutual Wealth Series at Twickenham Stadium (kick-off 2.30pm, live on Sky Sports 2). Jonny May lines up on the left wing.
