To the south, Seras was unable to make an impression on the Predil blockhouse with his artillery. Needing to use the Predil Pass to bring up his cavalry, artillery, and trains, Eugène sent three battalions from Tarvisio to help. On the 18th, Seras attacked the Grenzers with 8,500 troops and 12 guns. After a heroic last stand, Hermann and his garrison were killed to a man. The Franco-Italians lost 450 killed and wounded. After the defeat, Gyulay was unable to follow John's retreat to Graz. Instead, he followed the Drava River east and joined the archduke at Szentgotthárd in Hungary on 2 June. Gyulay missed the Battle of Raab on 14 June.
