I would love to have been at Malta 1565, as the Ottomans had gained a foothold in the main fort at Malta. Although wounded Grandmaster De Valette personally lead the counterattack with pike in hand and the hospitillars managed to drive the turks from there position.

Also from a safe place obviously, the carnage the longbows caused at crecy and then seeing the poor hapless genoese crossmen being run down by there own cavalry then to see those cavalry getting there arse handed to them by the dismounted english foot knights
