Do you capitalize this sentence after colon?

I'm using a style of capitalizing a complete sentence after a colon.

Here's the example sentence:

To minimize the time needed to traverse the large forest, I divided the fifty guards into three groups: twenty stood guard on the mountain, fifteen would lead the unwilling villagers back to the city, while the rest would accompany me back to the makeshift settlement near the mansion.

I don't know if this count as complete sentence, since if it has a construction like this instead:

To minimize the time needed to traverse the large forest, I divided the fifty guards into three groups equally: to stand guard on the mountain, to lead the unwilling villagers back to the city, and to accompany me back to the makeshift settlement near the mansion.

It won't be capitalized.

• Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking.

• Apart from the pedantic observation that 50 does not divide exactly by 3 in the second example, could you please give an example of where you think something should be capitalised after a colon? The question is not clear to me. Mar 13, 2022 at 2:57
