Blue Swiss
A Blue Swiss STOCK makes reference to the well-established financial company having stable earnings and no extensive liabilities in Switzerland. This term started to use in the financial slang in Geneva in order to difference between swiss blue chip and foreign blue chip.
Blue Swiss (Army)
The Spanish Army made use of permanently established foreign regiments. These comprised three Irish regiments (Irlanda, Hiberni and Ultonia); one Italian (Napoles) and five Swiss (Wimpssen, Reding, Betschart, Traxer and Preux).
In addition one regiment of the Royal Guard was recruited from Walloons. The last of these foreign regiments was disbanded in 1815, following recruiting difficulties during the Napoleonic Wars. One complication arising from the use of non-national troops occurred at the Battle of Bailén in 1808 when the "red Swiss" (so-called from their uniforms) of the invading French Army clashed bloodily with "Blue Swiss" in the Spanish service.
