In 1942 the greatest threat to allied shipping was the mighty German battleship, Tirpitz. Her vast size meant that the only dock on the Atlantic seaboard that could accommodate her was at St Nazaire.**So Operation Chariot was
The Anatinae subfamily contains three groups of ducks:
The
dabbling duck group, of worldwide distribution, include
usually 8 genera and some 50-60 living species.
Salvadori's Teal and the Crested Duck are sometimes
separated from Anas in monotypic genera.
The 3 known genera and 4 known species of moa-nalos
are all extinct. They formerly occurred on the Hawaiian
Islands and were derived from dabbling
ducks.
16 living or recently extinct species of
diving ducks, of worldwide distribution, in presently 3
genera; Marmaronetta was formerly included with the
dabbling ducks but is now treated here. Phylogenetic
analysis of the probably extinct Pink-headed Duck, previously treated separately in
Rhodonessa, has suggested that it belongs into
Netta (Livezey, 1998), but this approach has been
questioned (Collar et al., 2001). Molecular
studies, which would probably resolve this question,
have not been conducted to date.
