More importantly it then took the lives of over 300 servicemen to restore both the Falklands to British rule and the reputation of Mrs T.
As you don't specify whose servicemen, then it wouldn't be unreasonable to include the 655 dead Argentine servicemen either. Victims of Mrs T's actions and their Junta's reaction as much as our own dead.
P.S. Not servicemen, but three Falkland Islanders died in the conflict too.
