Brundtland battled back gamely to maintain his unbeaten record in the Qatar Prix Chaudenay at ParisLongchamp.
In giving the British raiders a flying start to the two-day Arc meeting, the Prix Niel winner relished every yard of the near two-mile trip.
William Buick attempted to make all on the son of Dubawi, but he looked a sitting duck a furlong out with challengers on either side.
While Mystic Sunrise dropped away, Lillian Russell, also in Godolphin silks for Henri-Alex Pantall, went about a neck up at one stage.
Just as he had last time though, Brundtland showed a likeable attitude and fought back to the front, winning cosily in the end.
Appleby said: “Coming into the race, we thought he would take all the beating and it was a very good ride from the front by William.
“It looks like the further he goes, the more improvement we’ll see. That’s it for him now and when he comes back in the spring, it will be over a mile and a half.
“Obviously I’m pleased we didn’t go for the Arc with him because he’s not ready for that. Another run in a race like the Chaudenay was the way for him, and we can build away next year.
“He showed his class in the closing stages and William thinks he’ll have no problem dropping back to a mile and a half.
“When he came into the straight and was challenged, I was confident he wouldn’t drop away, it was if something was good enough to pick him up.
“He showed his guts and determination and stuck it out well. We came here with confidence and he hasn’t let us down.”
Appleby his the bar in the Qatar Prix Dollar as Loxley was collared in the shadow of the post by Alignement.
Buick looked to have snatched the Group Two prize when his mount appeared on the outside of fellow British runner Fabricate, but Maxime Guyon produced the Carlos Laffon-Paris-trained winner with a perfectly-timed challenge to grab the prize by half a length.
Appleby said: “I feel William is being a bit hard on himself in saying he went too soon and you have to remember our horse was carrying a penalty against an older rival.
“He will be a good horse next year and when we get him started I’m not sure, though the Jebel Hatta could be on his agenda early in the year.”
Michael Bell was thrilled with Fabricate’s third place and added: “That was a career best for him and I imagine he’ll come back and engage in a similar programme next year.”
Simon Crisford’s Ostilio led home a British-trained one-two-three in the Qatar Prix Daniel Wildenstein.
Winner of the Britannia at Royal Ascot, Ostilio had also won at Doncaster last time out and Andrea Atzeni set out to make it a real test.
James Tate’s Hey Gaman set off in vain pursuit against the far rail, while Richard Hannon’s consistent Oh This Is Us made late gains.
Ostilio was not for catching though, with Oh This Is Us claiming second and Hey Gaman holding off the favourite Plumatic for third.
“He’s made the running all season and is a very tough horse that does it the hard way,” said Atzeni.
“Simon and his team have done a great job with him. The ground is good, but because of the watering it’s also patchy.”
