For the first hour, England's players were toying with their West German opponents.
Midfielder Alan Ball subsequently recalled taunting individual Germans such was the defending champions' dominance in the opening 60 minutes.
England, playing 4-4-2, began powerfully and impressively, with Alan Mullery getting a deserved opener just after the half-hour.
After playing a one-two with Francis Lee, Mullery played a long ball out to Eddie Newton on the right, before heading for the far post to meet the ensuing cross.
Horst-Dieter Hottges came on for Willi Schulz at half-time and made a much better job of containing the marauding Geoff Hurst, but Martin Peters still scored a second, again from a Newton cross.
Then Schoen took off Reinhard Libuda, who was making no impression, and brought on Jurgen Grabowski, who immediately did, running rings round a tiring Terry Cooper down the German right.
The game changed decisively.
Bonetti had never let England down before, but as the Germans found fresh heart, he proceeded to have a nightmare.
First, Franz Beckenbauer's innocuous shot somehow squeezed under the goalkeeper and into the net.
Then Ramsey erred by taking off Bobby Charlton and Martin Peters, supposedly to rest them for the semi-finals, and bringing on the more limited Colin Bell and Norman Hunter.
As time ticked away, Uwe Seeler got in behind a lumbering England defence and caught Bonetti in no-man's land with a header that looped high over him and into the net.
