(One of a series of weekday posts on the life of Winston S. Churchill.)
The following passage is found in the section headed "Political career before 1939" near the beginning of the Encyclopaedia Britannica Online’s Churchill biographical entry:
A self-assurance redeemed from arrogance only by a kind of boyish charm made Churchill from the first a notable House of Commons figure, but a speech defect, which he never wholly lost, combined with a certain psychological inhibition to prevent him from immediately becoming a master of debate. He excelled in the set speech, on which he always spent enormous pains, rather than in the impromptu; Lord Balfour, the Conservative leader, said of him that he carried “heavy but not very mobile guns.”Balfour’s metaphor is wonderful, isn’t it?
The entire Britannica Online entry's here. The Web page hosts, besides a fine text summary of Churchill's career, photos and audios. I think you'd all enjoy a look around, if you haven't been there already.
