The British government did not want to violate its agreement by attacking civilian targets outside combat zones and the French were even more concerned lest Bomber Command operations provoke a German bombing attack on France. Since the "Armée de l'Air" had few modern fighters and no defence network comparable to the British Chain Home radar stations, this left France powerless before the threat of a German bombing attack. The final problem was lack of adequate aircraft. The Bomber Command workhorses at the start of the war, the Vickers Wellington, Armstrong Whitworth Whitley and Handley Page Hampden/Hereford, had been designed as tactical-support medium bombers and none of them had enough range or ordnance capacity for anything more than a limited strategic offensive.
