Exasperated, the Pope increased taxes and raised additional forces and the war continued with Cardinal Antonio Barberini (Taddeo's brother) finding success against the Venetians and Modenese. But Papal forces suffered significant defeats in the area around Lake Trasimeno at the hands of the Tuscans (the "Battle of Mongiovino"). Fighting in the style typical of 17th-century Europe, by the latter half of 1643 neither side had made significant ground, though both sides had spent significant amounts of money perpetuating the conflict. It has been suggested that Pope Urban and forces loyal to the Barberini spent some 6 million thalers during the 4 years of the conflict that fell within Pope Urban's reign.
