In the ancient world

The earliest examples of expeditionary warfare come from the Sea Peoples, a term used for a confederation of seafaring raiders of the second millennium BC who sailed into the eastern shores of the Mediterranean, caused political unrest, and attempted to enter or control Egyptian territory during the late 19th dynasty, and especially during Year 8 of Ramesses III of the 20th dynasty.

The raiding tactics were expanded into the more complex expeditionary warfare operations by Alexander the Great who used naval vessels for both troop transporting and logistics in his campaigns against the Persian Empire.

The next exponents of expeditionary warfare in the ancient world of the Mediterranean Basin were the Carthaginians who introduced two entirely new dimensions to the use of naval forces by staging not only operations that combined naval and land troops, but also eventuated in combining strategic multi-national forces during the land phase of the operation when Hannibal in his most famous achievement at the outbreak of the Second Punic War marched an army, which included war elephants, from Iberia over the Pyrenees and the Alps into Northern Italy.

Following on the example of Carthage, the Romans used expeditionary operations extensively to expand their Empire and influence in the Mediterranean and beyond, including the Roman conquest of Britain which was not only a limited expeditionary operation, but one conceived to include long-term occupation and Roman settlement of the territories.

The Han dynasty of ancient China also famously used expeditionary warfare to deal with the nomadic Xiongnu people during the Han–Xiongnu War. Under the orders of Emperor Wu of Han, the Han launched numerous long-distance raids deep into Xiongnu territory. The exploits of famed Han generals Wei Qing and Huo Qubing were of particular note, with both recording multiple successful expeditions between the years 127 and 119 BC, eventually annexing the Hexi Corridor and expelling the Xiongnu from the Qilian Mountains. The expeditionary Han forces were primarily made up of cavalry and were typically arrayed in columns. They also frequently crossed vast distances–Huo Qubing is said to have travelled 2,000 li, roughly 620 miles/1000 km, during one of his raids.
