Nájera 1367

Red Cloud's War 1866-68

Operation Arctic Fox 1941

Panama 1989-90

Magnesia 190/189 BC

The Roman army and its allies faced the full might of the Seleucid Empire, under famed king Antiochus III, which included armoured cataphract cavalry, elephants, scythed chariots and the dreaded Macedonian pike phalanx. This will cover the fighting at Thermopylae and the sea battles of Eurymedon and Myonessus before covering the final showdown at Magnesia.

Nájera 1367

Part of the Castillian Civil War, this battle pitched King Peter of Castile against his half-brother Count Henry of Trastámara in a bid for the throne. The Black Prince of England backed Peter, supplying troops and fighting on his behalf. While the battle was a loss for Henry, the financial and political ramifications also caused problems for Peter and Edward.

Red Cloud’s War 1866–68

In early 1866, the US government promised Oglala Lakota leader Red Cloud that they would not send any more troops to secure the newly opened Bozeman Trail for westward-bound settlers. However, when the Army continued to build forts along the trail, Red Cloud gathered a coalition to drive them out. With no end in sight to the fighting by 1868, US officials had no choice but to give back the land to Red Cloud in a treaty.

Operation Arctic Fox 1941

Part of the larger Operation Silver Fox, this operation was conducted with the objective of advancing to block the Kirov Railway, connecting Murmansk to the main Soviet network. It was a joint operation between German and Finnish troops and they managed to start strong, but strong Soviet reinforcements halted their advance not far from the railway. Without the resources to continue, the Germans called off the operation.

Panama 1989–90

While initially on good terms, the relationship between General Manuel Noriega and the US intelligence agencies had deteriorated to the point of US invasion in 1989. Wanted for racketeering and drug trafficking, Noriega also annulled the results of the public elections, leading US President Bush to reinforce US troops. After roughly a month, Noriega was captured and sentenced to prison, and the Panama Defence Force was disbanded.
