Called by historians the "battle of the captains vs the generals", referring to the young Bulgarian army, whose highest rank went up to a captain, the battle of Slivnitza was a decisive factor in the victory of the Bulgarian army over the Serbians in 1885. It solidified the unification between the kingdom of Bulgaria and Eastern Rumelia.
The Battle of Bregalnica was fought between the Kingdom of Bulgaria army and the Kingdom of Serbia during the Second Balkan War.
A most violent battle ensued which lasted for several days; at some points the Bulgarians, thanks to the suddenness of their offensive, were temporarily successful, but gradually the Serbs regained the upper hand and by July 1 the Bulgarians were beaten.
The Battle of Slivnitsa was avenged by the battle of the Bregalnica, the defeat which lurked upon the Serbian army and, which was the cause of the optimism of Turkish central command and its Vardar Army operational plan during the First Balkans War.
