Struthas, was sent out to take command. Struthas pursued an anti-Spartan policy, prompting the Spartans to order their commander in the region, Thibron, to attack him. Thibron successfully ravaged Persian territory for a time, but was killed along with much of his army when Struthas ambushed one of his poorly organized raiding expeditions. Thibron was later replaced by Diphridas, who raided more successfully, securing a number of small successes and even capturing Struthas's son-in-law, but never achieved any dramatic results. Lechaeum and the seizure of Corinth At Corinth, the democratic party continued to hold the city proper, while the exiles and their Spartan supporters held Lechaeum, from where they raided the Corinthian countryside. In 391 BC, Agesilaus campaigned in the area, successfully seizing several fortified points, along with a large number of prisoners and amounts of booty. While Agesilaus was in camp preparing to sell off his spoils, the Athenian general Iphicrates, with a force composed almost entirely of light troops and peltasts (javelin throwers), won a decisive victory against the Spartan regiment that had been stationed at Lechaeum in the Battle of Lechaeum. During the battle, Iphicrates took advantage of the Spartans' lack of peltasts to repeatedly harass the regiment with hit-and-run attacks, wearing the Spartans down until they broke and ran, at which point a number of them were slaughtered. Agesilaus returned home shortly after these events, but Iphicrates continued to campaign around Corinth, recapturing many of the strong points which the Spartans had previously taken, although he was unable to retake Lechaeum. He also campaigned against Phlius and Arcadia, decisively defeating the Phliasians and plundering the territory of the Arcadians when they refused to engage his troops. After this victory, an Argive army came to Corinth, and, seizing the acropolis, effected the merger of Argos and Corinth. The border stones between Argos and Corinth were torn down, and the citizen bodies of the two cities were merged. Later land campaigns After Iphicrates's victories near Corinth, no more major land campaigns were conducted in that region. Campaigning continued in the Peloponnese and the northwest. Agesilaus had campaigned successfully in Argive territory in 391 BC, and he launched two more major expeditions before the end of the war. In the first of these, in 389 BC, a Spartan expeditionary force crossed the Gulf of Corinth to attack Acarnania, an ally of the anti-Spartan coalition. After initial difficulties in coming
