In 344 BC Demosthenes travelled to the Peloponnese, to detach as many cities as possible from Macedon's influence, but his efforts were generally unsuccessful. Most of the Peloponnesians saw Philip as the guarantor of their freedom and sent a joint embassy to Athens to express their grievances against Demosthenes' activities. In response, Demosthenes delivered the "Second Philippic", a vehement attack against Philip. In 343 BC Demosthenes delivered "On the False Embassy" against Aeschines, who was facing a charge of high treason. Nonetheless, Aeschines was acquitted by the narrow margin of thirty votes by a jury which may have numbered as many as 1,501.* D. M. MacDowell, "Demosthenes the Orator", ch. 12 "(in fine)".</ref>
