As the fighting moved on to Germany, Dumbo was connected to an inland pipeline system that was extended from Boulogne to Antwerp, Eindhoven and ultimately Emerich. Dumbo surpassed its target of 1 million imperial gallons (4.5 million litres) (about 3,000 long tons (3,000 t)) per day on 15 March 1945, and by 3 April the Dumbo lines were delivering 4,500 long tons (4,600 t) a day to the Rhine.[46] New lines continued to be laid, the last one being laid on 24 May.[41]
