In mid-June, the Pragmatic army arrived at Aschaffenburg, on the north bank of the River Main. Here they were joined by George II, who was attending the coronation of a new Elector of Mainz in Wiesbaden. By late June, the Allies were running short of supplies; the nearest depot was at Hanau, the road to which ran through Dettingen (modern Karlstein am Main). Here, French commander, the duc de Noailles, positioned 23,000 troops under his nephew, the duc de Gramont, whose mistakes prevented an Allied defeat.
