According to this dictionary, the verb "force" seems to have these two usage patterns:
p1. force somebody into doing something
p2. force somebody into something
Examples from that dictionary illustrating the two usages are:
e1 The President was forced into resigning.
e2 Ill health forced him into early retirement.
Example sentence e2 suggests that pattern p2 can only be used with a state noun (in retirement) and not an action noun (resignation). So, does that mean that this:
The president was forced into resignation.
is wrong?

All three sentences can have the same meaning:
