Then, Franco decided to send heavy reinforcements to the Ebro’s front (eight divisions, more than 140 bombers and 100 fighters) and passed the order for the dams at Tremp and Camarasa to be opened. The flood water destroyed the pontoon bridges, although the Republican engineers managed to repair them within two days. Furthermore, the "Condor Legion" and the "Aviazione Legionaria" started to bomb and destroy the pontoon bridges each day, although the Republican engineers managed to repair them each night. Because of this, only 22 tanks and a handful of artillery managed to cross the Ebro River, and Republican troops began running low on supplies, ammunition and drinking water.
