Can an independent clause be interrupted by a conjunction without a comma and still be an independent clause? e.g.:

He poured me another drink and I drank it.
Max climbed onto his horse and we rode away.

Would these be considered compound sentences? Or are these sentences grammatically incorrect?

As far as I know, compound sentences must include a comma. Is this information incorrect?

Yes, that is a compound sentence. A clause has a subject and a verb, and can stand on its own, and since both clauses can stand by themselves, they are both independent clauses.

    Did you want to address the comma question? Jan 16 at 23:04

You have two independent clauses joined by a coordinating conjunction (a compound sentence) whether you use a comma or not. Independent clauses don’t much care about punctuation, but stylists tend to:

When independent clauses are joined by and, but, or, so, yet, or any other coordinating conjunction, a comma usually precedes the conjunction. If the clauses are very short and closely connected, the comma may be omitted . . . unless the clauses are part of a series. These recommendations apply equally to imperative sentences . . .

Here are a couple of the offered examples:

All watches display the time, and some of them do so accurately.
Electra played the guitar and Tambora sang.

  • Some prescriptivists might insist on a comma in CMOS’s second example sentence. However, even they usually don’t object when both clauses share a modifier, e.g.: “At the party, Electra played the guitar and Tambora sang.” Jan 17 at 1:09
