Post by our_kid2000question about the battle at Montecasino,
why didn't the Allies simply go around the place rather
than slog it out like they did?
Probably best to remember some basics before the particulars.
When the enemy has a well defensed position,
a good leader must consider several approaches.
Going around is valid if there is a reasonable way to
go around, and that position is not a threat to you.
So for example for many Japanese held well fortified islands,
once their offensive threat was neutralized (no ships or
airfields) they could be left to "wither on the vine."
Monte Cassino was not like that.
The Allies were pushing up the boot of Italy with the
main desires of 1) putting pressure on Germany and
2) removing Italy from the Axis (and capturing Rome
was important to this psychologically, politically &
logistically).
During the winter of 1943-44 Axis forces held quite
defensible positions along the Gustav Line. One of
the strongpoints of this was the hill at Monte Cassino.
This hill overlooked (and thus to a very large extent
controlled ((by observation directing air and artillery,
and by direct fire)) the important avenues of movement.
Try finding a map to make better sense of my words.
Italy in this area is quite hilly with few easy routes to
move armies and the supplies they need north.
Monte Cassino overlooks the Liri river and valley,
route 6, railroad tracks, and the Garigliano and
Rapido valleys. It is very hard to avoid these and get
to Rome. So in December '43 Allies started trying and
could not.
In January '44 they tried 'going around' with the amphibian.
landings at Anzio, but this also had problems. It was
decided that the main force had to push through to
link up with the Anzio force. So from January until
18 May 1944 many efforts were made and the hill was
finally taken.
Germany then had to withdraw through various defensive
positions (Viterbo line, Trasimene line, Arno line), to the
quite strong Gothic line in August.
As part of this Rome was 'given up' on 4 June.
Sometimes there is just no avoiding a tough hard fight.
